boot: change some arch ifdefs to feature ifdefs

Browse Source 
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_SYS_BOOT_<FEATURE> defines instead.

CONFIG_SYS_BOOT_RAMDISK_HIGH
CONFIG_SYS_BOOT_GET_CMDLINE
CONFIG_SYS_BOOT_GET_KBD

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

all data for the Linux kernel must be between "bootm_low"
and "bootm_low" + CONFIG_SYS_BOOTMAPSZ.
- CONFIG_SYS_BOOT_RAMDISK_HIGH:
Enable initrd_high functionality. If defined then the
initrd_high feature is enabled and the bootm ramdisk subcommand
is enabled.
- CONFIG_SYS_BOOT_GET_CMDLINE:
Enables allocating and saving kernel cmdline in space between
"bootm_low" and "bootm_low" + BOOTMAPSZ.
- CONFIG_SYS_BOOT_GET_KBD:
Enables allocating and saving a kernel copy of the bd_info in
space between "bootm_low" and "bootm_low" + BOOTMAPSZ.
- CONFIG_SYS_MAX_FLASH_BANKS:
Max number of Flash memory banks
