powerpc: Include asm/firmware.h in all users of firmware_has_feature()

Trying to remove asm/ppc_asm.h from all places that don't need it
leads to several failures linked to firmware_has_feature().

To fix it, include asm/firmware.h in all files using
firmware_has_feature()

All users found with:

	git grep -L "firmware\.h" ` git grep -l "firmware_has_feature("`
