ppc: Fix rfi/rfid/hrfi/... emulation
This reworks emulation of the various "rfi" variants. I removed
some masking bits that I couldn't make sense of, the only bit that
I am aware we should mask here is POW, the CPU's MSR mask should
take care of the rest.
This also fixes some problems when running 32-bit userspace under
a 64-bit kernel.
This patch broke 32bit OpenBIOS when run under a 970 cpu. A fix was
proposed here :

[dwg: Remove hunk which disabled rfi on 64-bit CPUS. The change was
correct, but we need to fix OpenBIOS before applying it]
