The rs6000_get_timebase expander expands to rs6000_mftb_di for
TARGET_POWERPC64, so the define_insn should allow it too.

This fixes gcc.target/powerpc/ppc-get-timebase.c for -m32 -mpowerpc64.

Okay for mainline?

	* config/rs6000/rs6000.md (rs6000_mftb_<mode>): Use mode iterator
	GPR instead of P.
