Change the pmap_enter api to pass down an argument that indicates
the access type that caused this mapping. This is to simplify pmaps
with mod/ref emulation (none for the moment) and in some cases speed
up pmap_is_{referenced,modified}.
At the same time, clean up some mappings that had too high protection.
XXX - the access type is incorrect in old vm, it's only used by uvm and MD code.
The actual use of this in pmap_enter implementations is not in this commit.
