Log Message:
mi pmap: pmap_clear_attribute should check cached value of the attribute

The pmap_clear_attribute implementation used by the MI pmap should
check the cached valued of the attribute as well as any value held
in the PTE(s).

Some emulation implementations require this as some operations, e.g
changing page mappings to RO, can lose PTE attribute information.
