powerpc: make additional room in exception vector area

The FWNMI region is fixed at 0x7000 and the vector are now overflowing
that with allmodconfig. Fix that by moving slb_miss_realmode code out
of that region as it doesn't need to be that close to the call sites
(it is a _GLOBAL function)

Fixes this build error:
