target-ppc: mmu_ctx_t should not be a global type
mmu_ctx_t is currently defined in cpu.h. However it is used for temporary
information relating to mmu translation, and is only used in mmu_helper.c
and (now) mmu-hash{32,64}.c. Furthermore it contains information which
should be specific to particular MMU types. Therefore, move its definition
to mmu_helper.c. mmu-hash{32,64}.c are converted to use new data types
private to the relevant MMUs (identical to mmu_ctx_t for now, but that will
change in future patches).
