ARM pmap fixes.

a)  nocache-remap problem

   When a page is remapped into a non-cacheable virtual memory region there
   was no associated write-back invalidate operation performed. We remove
   writeback of the original buffer size from bus_dmamem_alloc() and add
   appropriate L1/L2 flush operation.

b) missing write-back invalidate operation

   In pmap_kremove a page is removed so we must do a write-back
   invalidate operation aligned to the page virtual address.
