powerpc: ppc4xx: remove korat board support

This has not been converted to Generic Board, so should be removed.
(See doc/README.generic-board for details.)

-The Korat board has two NOR flashes, FLASH0 and FLASH1, which are connected to
-chip select 0 and 1, respectively.  FLASH0 contains 16 MiB, and is mapped to
-addresses 0xFF000000 - 0xFFFFFFFF as U-Boot Flash Bank #2.  FLASH1 contains
-from 16 to 128 MiB, and is mapped to 0xF?000000 - 0xF7FFFFFF as U-Boot Flash
-Bank #1 (with the starting address depending on the flash size detected at
-runtime).  The write-enable pin on FLASH0 is disabled, so the contents of FLASH0
-cannot be modified in the field.  This also prevents FLASH0 from executing
-commands to return chip information, so its configuration is hard-coded in
-U-Boot.
-
-There are two versions of U-Boot for Korat: "permanent" and "upgradable".  The
-permanent U-Boot is pre-programmed at the top of FLASH0, e.g., at addresses
-0xFFFA0000 - 0xFFFFFFFF for the current 384 KiB size.  The upgradable U-Boot is
-located 256 KiB from the top of FLASH1, e.g. at addresses 0xF7F6000 - 0xF7FC0000
-for the current 384 KiB size.  FLASH1 addresses 0xF7FE0000 - 0xF7FF0000 are
-used for the U-Boot environmental parameters, and addresses 0xF7FC0000 -
-0xF7FDFFFF are used for the redundant copy of the parameters.  These locations
-are used by both versions of U-Boot.
-
-On booting, the permanent U-Boot in FLASH0 begins executing.  After performing
-minimal setup, it monitors the state of the board's Reset switch (GPIO47).  If
-the switch is sensed as open before a timeout period, then U-Boot branches to
-address 0xF7FBFFFC.  This causes the upgradable U-Boot to execute from the
-beginning.  If the switch remains closed thoughout the timeout period, the
-permanent U-Boot activates the on-board buzzer until the switch is sensed as
-opened.  It then continues to execute without branching to FLASH1.  The effect
-of this is that normally the Korat board boots its upgradable U-Boot, but, if
-this has been corrupted, the user can boot the permanent U-Boot, which can then
-be used to erase and reload FLASH1 as needed.
-
-Note that it is not necessary for the permanent U-Boot to have all the latest
-features, but only that it have sufficient functionality (working "tftp",
-"erase", "cp.b", etc.) to repair FLASH1.  Also, the permanent U-Boot makes no
-assumptions about the size of FLASH1 or the size of the upgradable U-Boot: it is
-sufficient that the upgradable U-Boot can be started by a branch to 0xF7FBFFFC.
-
-The build sequence:
-
-	make korat_perm_config
-	make all
-
-builds the permanent U-Boot by selecting loader file "u-boot.lds" and defining
-preprocessor symbol "CONFIG_KORAT_PERMANENT".  The default build:
-
-	make korat_config
-	make all
-
-creates the upgradable U-Boot by selecting loader file "u-boot-F7FC.lds" and
-leaving preprocessor symbol "CONFIG_KORAT_PERMANENT" undefined.

-The CompactFlash(R) controller on the Korat board provides a hi-speed USB
-interface.  This may be connected to either a dedicated port on the on-board
-USB controller, or to a USB port on the PowerPC 440EPx processor.  The U-Boot
-environment variable "korat_usbcf" can be used to specify which of these two
-USB host ports is used for CompactFlash.  The valid setting for the variable are
-the strings "pci" and "ppc".  If the variable defined and set to "ppc", then the
-PowerPC USB port is used.  In all other cases the on-board USB controller is
-used, but if "korat_usbcf" is defined but is set to a string other than the two
-valid options, a warning is also issued.
