[ARM] Clean up map_desc structure

- remove LAST_DESC in favour of passing the array size to iotable_init
- replace domain and permission bits/cache attributes with a generic
  "type", which can be easily converted to the required domain and
  permission bits/cache attributes at run time.  It also removes the
  possibility for getting such things wrong and (accidentally)
  allowing all user space to fiddle with devices directly.
