[U-Boot] [PATCH 3/5] boot: change some arch ifdefs to feature ifdefs

[John Rigby]

The routines boot_ramdisk_high, boot_get_cmdline and boot_get_kbd
are currently enabled by various combinations of CONFIG_M68K,
CONFIG_POWERPC and CONFIG_SPARC.

Use CONFIG_<FEATURE> defines instead.

CONFIG_BOOT_RAMDISK_HIGH
CONFIG_BOOT_GET_CMDLINE
CONFIG_BOOT_GET_KBD

Define these as appropriate in arch/include/asm/config.h files.
