ppc32: Make use of cpufeatures in some flush rountines

This is based on an observation from Pantelis Antoniou.  We get
a minor speedup of flush_icache_range, __flush_dcache_icache and
__flush_dcache_icache_phys, in that we do not need to do this on
CPUs with a unified cache (601), so check for that feature bit
instead of a PVR check.
