powerpc: Annotate endianness of various variables and functions
Sparse reports several endianness warnings on variables and functions
that are consistently treated as big endian. There are no
multi-endianness shenanigans going on here so fix these low hanging
fruit up in one patch.
All changes are just type annotations; no endianness switching
operations are introduced by this patch.
