MFC r257648, r257649, r257660:

  Begin reducing code duplication in arm pmap.c and pmap-v6.c by factoring
  out common code related to mapping device memory into a new devmap.c file.

  Remove the growing duplication of code that used pmap_devmap_find_pa() and
  then did some math with the returned results to generate a virtual address,
  and likewise in reverse to get a physical address.  Now there are a pair
  of functions, arm_devmap_vtop() and arm_devmap_ptov(), to do that.  The
  bus_space_map() implementations are rewritten in terms of these.

  Move remaining code and data related to static device mapping into the
  new devmap.[ch] files.  Emphasize the MD nature of these things by using
  the prefix arm_devmap_ on the function and type names (already a few of
  these things found their way into MI code, hopefully it will be harder to
  do by accident in the future).
