In order to do this a new platform_has_feature call is introduced (in a subsequent patch) to make this check. To avoid having to re-define bits in the architecture vector the bits are moved to prom.h. This patch is the first step in implementing the platform_has_feature call by simply moving the bit definitions from prom_init.c to asm/prom.h. There are no functional.
