MIPS: drop incaip board

This is dead hardware and no one is interested in making the
necessary changes for upcoming features like generic board or
driver model.

-Flash programming on the INCA-IP board is complicated because of the
-EBU swapping unit. A BDI2000 can be used for flash programming only
-if the EBU swapping unit is enabled; otherwise it will not detect the
-flash memory. But the EBU swapping unit is disadbled after reset, so
-if you program some code to flash with the swapping unit on, it will
-not be runnable with the swapping unit off.
-
-The consequence is that you have to write a pre-swapped image to
-flash using the BDI2000. A simple host-side tool "inca-swap-bytes" is
-provided in the "tools/" directory. Use it as follows:
-
-	bash$ ./inca-swap-bytes <u-boot.bin >u-boot.bin.swp
-
-Note that the current BDI config file _disables_ the EBU swapping
-unit for the flash bank 0. To enable it, (this is required for the
-BDI flash commands to work) uncomment the following line in the
-config file:
-
-	;WM32   0xb8000260      0x404161ff ; Swapping unit enabled
-
-and comment out
-
-	WM32    0xb8000260      0x004161ff ; Swapping unit disabled
-
-Alternatively, you can use "mm 0xb8000260 <value>" commands to
-enable/disable the swapping unit manually.
-
-Just for reference, here is the complete sequence of actions we took
-to install a U-Boot image into flash.
-
-    1. ./inca-swap-bytes <u-boot.bin >u-boot.bin.swp
-
-    2. From BDI:
-
-	mm 0xb8000260  0x404161ff
-	erase 0xb0000000
-	erase 0xb0010000
-	prog 0xb0000000 /tftpboot/INCA/u-boot.bin.swp bin
-	mm 0xb8000260 0x004161ff
-	go 0xb0000000
-
-
-Ethernet autonegotiation needs some time to complete. Instead of
-delaying the boot process in all cases, we just start the
-autonegotiation process when U-Boot comes up and that is all. Most
-likely, it will complete by the time the network transfer is
-attempted for the first time. In the worst case, if a transfer is
-attempted before the autonegotiation is complete, just a single
-packet would be lost resulting in a single timeout error, and then
-the transfer would proceed normally. So the time that we would have
-lost unconditionally waiting for the autonegotiation to complete, we
-have to wait only if the file transfer is started immediately after
-reset. We've verified that this works for all the clock
-configurations.
