        syssrc/sys/arch/arm/arm32: pmap.c

Log Message:
Add a pmap_map_ptes function to map another process page table entries into the 
current pmap (similair to pmap_pte) but this allows multiple use of it, rather 
than repeated calls of pmap_pte for pte, map_ptes returns a pointer to the va 
where the entries were mapped so it can be reused ptes can be found by indexing 
into it.

Update some of the functions that use pmap_pte to pmap_map_ptes.

Note that there's a dummy macro for pmap_unmap_ptes, this is because at some 
point locking will be needed, so we need to be able to unlock them.

Performance gain seems to be minimal, however long term it should help improve 
things.

This is similair to the i386 pmap_map_ptes, however it's based on a version 
from Richard Earnshaw.
