extend uvm_page_physload to have the ability to add "device" pages to the
system.
This is needed in the case where you need managed pages so you can
handle faulting and pmap_page_protect() on said pages when you manage
memory in such regions (i'm looking at you, graphics cards).
these pages are flagged PG_DEV, and shall never be on the freelists,
assert this. behaviour remains unchanged in the non-device case,
specifically for all archs currently in the tree we panic if called
after bootstrap.
ok art@, kettenis@, ariane@, beck@.
