powerpc: Get USE_STRICT_MM_TYPECHECKS working again
The typesafe version of the powerpc pagetable handling (with
USE_STRICT_MM_TYPECHECKS defined) has bitrotted again. This patch
makes a bunch of small fixes to get it back to building status.
It's still not enabled by default as gcc still generates worse
code with it for some reason.
