Subject: perf dwarf-regs: Move powerpc dwarf-regs out of arch

Move arch/powerpc/util/dwarf-regs.c to util/dwarf-regs-powerpc.c and
compile in unconditionally. get_arch_regstr is redundant when EM_NONE
is treated as EM_HOST so remove and update dwarf-regs.c conditions.
Make get_powerpc_regs unconditionally available whwn libdw is.
