drivers/net: delete old DEC depca ISA drivers support.

These are old ISA 10Mbit cards from the 1st 1/2 of the 1990s and
required manual jumper settings in order to configure them.  Here
we remove them on the premise that they are no longer used in any
modern 3.9+ kernels.

-/*  depca.c: A DIGITAL DEPCA & EtherWORKS ethernet driver for linux.

-
-    This driver is written for the Digital Equipment Corporation series
-    of DEPCA and EtherWORKS ethernet cards:
-
-        DEPCA       (the original)
-    	DE100
-    	DE101
-	DE200 Turbo
-	DE201 Turbo
-	DE202 Turbo (TP BNC)
-	DE210
-	DE422       (EISA)
-
-    The  driver has been tested on DE100, DE200 and DE202 cards  in  a
-    relatively busy network. The DE422 has been tested a little.
-
-    This  driver will NOT work   for the DE203,  DE204  and DE205 series  of
-    cards,  since they have  a  new custom ASIC in   place of the AMD  LANCE
-    chip.  See the 'ewrk3.c'   driver in the  Linux  source tree for running
-    those cards.
-
-    I have benchmarked the driver with a  DE100 at 595kB/s to (542kB/s from)
-    a DECstation 5000/200.

-
-    The  driver was originally based  on   the 'lance.c' driver from  Donald
-    Becker   which  is included with  the  standard  driver distribution for
-    linux.  V0.4  is  a complete  re-write  with only  the kernel  interface
-    remaining from the original code.

-
-    Peter Bauer's depca.c (V0.5) was referred to when debugging V0.1 of this
-    driver.
-
-    The original DEPCA  card requires that the  ethernet ROM address counter
-    be enabled to count and has an 8 bit NICSR.  The ROM counter enabling is
-    only  done when a  0x08 is read as the  first address octet (to minimise
-    the chances  of writing over some  other hardware's  I/O register).  The
-    NICSR accesses   have been changed  to  byte accesses  for all the cards
-    supported by this driver, since there is only one  useful bit in the MSB
-    (remote boot timeout) and it  is not used.  Also, there  is a maximum of
-    only 48kB network  RAM for this  card.  My thanks  to Torbjorn Lindh for
-    help debugging all this (and holding my feet to  the fire until I got it
-    right).
-
-    The DE200  series  boards have  on-board 64kB  RAM for  use  as a shared
-    memory network  buffer. Only the DE100  cards make use  of a  2kB buffer
-    mode which has not  been implemented in  this driver (only the 32kB  and
-    64kB modes are supported [16kB/48kB for the original DEPCA]).
-
-    At the most only 2 DEPCA cards can  be supported on  the ISA bus because
-    there is only provision  for two I/O base addresses  on each card (0x300
-    and 0x200). The I/O address is detected by searching for a byte sequence
-    in the Ethernet station address PROM at the expected I/O address for the
-    Ethernet  PROM.   The shared memory  base   address  is 'autoprobed'  by
-    looking  for the self  test PROM  and detecting the  card name.   When a
-    second  DEPCA is  detected,  information  is   placed in the   base_addr
-    variable of the  next device structure (which  is created if necessary),
-    thus  enabling ethif_probe  initialization  for the device.  More than 2
-    EISA cards can  be  supported, but  care will  be  needed assigning  the
-    shared memory to ensure that each slot has the  correct IRQ, I/O address
-    and shared memory address assigned.
-
-    ************************************************************************
-
-    NOTE: If you are using two  ISA DEPCAs, it is  important that you assign
-    the base memory addresses correctly.   The  driver autoprobes I/O  0x300
-    then 0x200.  The  base memory address for  the first device must be less
-    than that of the second so that the auto probe will correctly assign the
-    I/O and memory addresses on the same card.  I can't think of a way to do
-    this unambiguously at the moment, since there is nothing on the cards to
-    tie I/O and memory information together.
-
-    I am unable  to  test  2 cards   together for now,    so this  code   is
-    unchecked. All reports, good or bad, are welcome.
-
-    ************************************************************************
-
-    The board IRQ   setting must be  at an  unused IRQ which  is auto-probed
-    using Donald Becker's autoprobe routines. DEPCA and DE100 board IRQs are
-    {2,3,4,5,7}, whereas the  DE200 is at {5,9,10,11,15}.  Note that IRQ2 is
-    really IRQ9 in machines with 16 IRQ lines.
-
-    No 16MB memory  limitation should exist with this  driver as DMA is  not
-    used and the common memory area is in low memory on the network card (my
-    current system has 20MB and I've not had problems yet).
-
-    The ability to load this driver as a loadable module has been added. To
-    utilise this ability, you have to do <8 things:
-
-    0) have a copy of the loadable modules code installed on your system.
-    1) copy depca.c from the  /linux/drivers/net directory to your favourite
-    temporary directory.
-    2) if you wish, edit the  source code near  line 1530 to reflect the I/O
-    address and IRQ you're using (see also 5).
-    3) compile  depca.c, but include -DMODULE in  the command line to ensure
-    that the correct bits are compiled (see end of source code).
-    4) if you are wanting to add a new  card, goto 5. Otherwise, recompile a
-    kernel with the depca configuration turned off and reboot.
-    5) insmod depca.o [irq=7] [io=0x200] [mem=0xd0000] [adapter_name=DE100]
-       [Alan Cox: Changed the code to allow command line irq/io assignments]
-       [Dave Davies: Changed the code to allow command line mem/name
-                                                                assignments]
-    6) run the net startup bits for your eth?? interface manually
-    (usually /etc/rc.inet[12] at boot time).
-    7) enjoy!
-
-    Note that autoprobing is not allowed in loadable modules - the system is
-    already up and running and you're messing with interrupts.
-
-    To unload a module, turn off the associated interface
-    'ifconfig eth?? down' then 'rmmod depca'.
-
-    To assign a base memory address for the shared memory  when running as a
-    loadable module, see 5 above.  To include the adapter  name (if you have
-    no PROM  but know the card name)  also see 5  above. Note that this last
-    option  will not work  with kernel  built-in  depca's.
-
-    The shared memory assignment for a loadable module  makes sense to avoid
-    the 'memory autoprobe' picking the wrong shared memory  (for the case of
-    2 depca's in a PC).
-
-    ************************************************************************
-    Support for MCA EtherWORKS cards added 11-3-98. (MCA since deleted)
-    Verified to work with up to 2 DE212 cards in a system (although not
-      fully stress-tested).
