  Enhance pmap_mapdev_attr().  Take advantage of recent enhancements to
  pmap_change_attr() in order to use the direct map for any cache mode, not
  just write-back mode.
  It is worth noting that this change also eliminates a situation in which we
  have two mappings to the same physical memory with different cache modes.
