ArmLib/ArmV7Mmu: use 64-bit type for mapping region size
The way the v7 MMU code is invoked by the Xen port is somewhat of
a pathological case, since it describes its physical memory space
using a single cacheable region that covers the entire addressable
range. When clipping this region to the part that is 1:1 addressable,
we end up with a region of exactly 4 GB in size, which just exceeds
the range of the UINT32 variable we use in FillTranslationTable() to
track our progress while populating the page tables. So promote it
to UINT64 instead.
