[PATCH] rs6000: Fix mftb for -m32 -mpowerpc64

- Subject: [PATCH] rs6000: Fix mftb for -m32 -mpowerpc64
- Authentication-results: sourceware.org; auth=none
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.
