powerpc: Remove support for PowerPC 601
PowerPC 601 has been retired.
Remove all associated specific code.
CPU_FTRS_PPC601 has CPU_FTR_COHERENT_ICACHE and CPU_FTR_COMMON.
CPU_FTR_COMMON is already present via other CPU_FTRS.
None of the remaining CPU selects CPU_FTR_COHERENT_ICACHE.
So CPU_FTRS_PPC601 can be removed from the possible features,
hence can be removed completely.
