target-ppc: Convert mmu-hash{32,64}.[ch] from CPUPPCState to PowerPCCPU

Like a lot of places these files include a mixture of functions taking
both the older CPUPPCState *env and newer PowerPCCPU *cpu.  Move a step
closer to cleaning this up by standardizing on PowerPCCPU, except for the
helper_* functions which are called with the CPUPPCState * from tcg.

Callers and some related functions are updated as well, the boundaries of
what's changed here are a bit arbitrary.
