Kill pmap_phys_address(), and force every driver's mmap() routine to return
a physical address [more precisely, something suitable to pass to pmap_enter()'sphysical address argument].
This allows MI drivers to implement mmap() routines without having to know
about the pmap_phys_address() implementation and #ifdef obfuscation.
