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.
