target-ppc: Handle memory-forced I/O controller access
On at least the PowerPC 601, a direct-store (T=1) with bus unit ID 0x07F
is special-cased as memory-forced I/O controller access. It is supposed
to be checked immediately if T=1, bypassing all protection mechanisms
and acting cache-inhibited and global.

Simplified by avoiding reindentation. Added explanatory comments.
