[POWERPC] Consolidate feature fixup code
There are currently two versions of the functions for applying the feature fixups, one for CPU features and one for firmware features. In addition, they are both in assembly and with separate implementations for 32 and 64 bits. identify_cpu() is also implemented in assembly and separately for 32 and 64 bits. This patch replaces them with a pair of C functions. The call sites are slightly moved on ppc64 as well to be called from C instead of from assembly, though it's a very small change, and thus shouldn't cause any problem.
