ARM: drop unsupported 'trab' board

The 'trab' board configuration is broken, and there is nobody who is
interested and willing to fix it.  Drop it.

This includes support for VFD displays which have always been used by
this board only.

-The TRAB keyboard implementation is similar to that for LWMON and
-R360MPI boards. The only difference concerns key naming. There are 4
-keys on TRAB: 1, 2, 3, 4.
-
-1) The "kbd" command provides information about the current state of
-   the keys. For example,
-
-	TRAB # kbd
-	Keys: 1 0 1 0
-
-   means that keys 1 and 3 are pressed. The keyboard status is also
-   stored in the "keybd" environment variable. In this example we get
-
-	keybd=1010
-
-2) The "preboot" variable is set according to current environment
-   settings and keys pressed. This is an example:
-
-	TRAB # setenv magic_keys XY
-	TRAB # setenv key_magicX 12
-	TRAB # setenv key_cmdX echo ## Keys 1 + 2 pressed ##\;echo
-	TRAB # setenv key_magicY 13
-	TRAB # setenv key_cmdY echo ## Keys 1 + 3 pressed ##\;echo
-
-   Here "magic_keys=XY" means that the "key_magicX" and "key_magicY"
-   variables will be checked for a match. Each variable "key_magic*"
-   defines a set of keys. In the our example, if keys 1 and 3 are
-   pressed during reset, then "key_magicY" matches, so the "preboot"
-   variable will be set to the contents of "key_cmdY":
-
-	preboot=echo ## Keys 1 + 3 pressed ##;echo
-
-3) The TRAB board has optional modem support. When a certain key
-   combination is pressed on the keyboard at power-on, the firmware
-   performs the necessary initialization of the modem and allows for
-   dial-in. The key combination is specified in the
-   "include/configs/trab.h" file. For example:
-
-	#define        CONFIG_MODEM_KEY_MAGIC  "23"
-
-   means that modem will be initialized if and only if both keys 2, 3
-   are pressed. Note that the format of this string is similar to the
-   format of "key_magic*" environment variables described above.
