arm32: remove memmap_notinit bookkeeping

Removes the bookkeeping of whether memory map has been initialized or
not using the memmap_notinit variable. Memory map is always initialized
before any core_va2pa() or core_pa2va() is performed so the bookkeeping
doesn't do much good.

The variable was updated with caches disabled while other CPUs might have
caches enabled. This can result in unexpected problems.
