target/ppc: Unexport some functions from mmu-book3s-v3.h

The ppc_hash64_hpt_base() and ppc_hash64_hpt_mask() functions are
mostly used by mmu-hash64.c only but there is one call to
ppc_hash64_hpt_mask() in hw/ppc/spapr_vhyp_mmu.c.in a helper function
that can be moved to mmu-hash64.c which allows these functions to be
removed from the header.
