Remove/update old generic-board documentation and warning

Remove the warning from the Makefile, since boards that do not use generic
board will no longer build. Also update documentation.

-Supported Architectures
-------------------------
-
-If you are unlucky then your architecture may not support generic board.
-The following architectures are supported now:
-
-   arc
-   arm
-   avr32
-   blackfin
-   m68k
-   microblaze
-   mips
-   nios2
-   powerpc
-   sandbox
-   x86

-If your architecture is not supported, you need to select
-HAVE_GENERIC_BOARD in arch/Kconfig
-and test it with a suitable board, as follows.
-
-
-Adding Support for your Board
------------------------------
-
-To enable generic board for your board, define CONFIG_SYS_GENERIC_BOARD in
-your board config header file.
-
-Test that U-Boot still functions correctly on your board, and fix any
-problems you find. Don't be surprised if there are no problems - generic
-board has had a reasonable amount of testing with common boards.
