target-ppc: Disentangle get_segment()

The poorly named get_segment() function handles most of the address
translation logic for hash-based MMUs.  It has many ugly conditionals on
whether the MMU is 32-bit or 64-bit.

This patch splits the function into 32 and 64-bit versions, using the
switch on mmu_type that's already in the caller
(get_physical_address()) to select the right one.  Most of the
original function remains in mmu_helper.c to support the 6xx software
loaded TLB implementations (cleaning those up is a project for another
day).
