The ARM 32-bit and 64-bit MMU code makes heavy use of uint32_t and
uint64_t respectively.
We can't use ulong for common code between them as u32 is an unsigned long
and u64 is a unsigned long long and pointers to them can not be implicitly
converted. As we don't want to rewrite all MMU code to use ullong, let's
just define a new mmu_addr_t, which can be used in code that should be
callable from either ISA.
