reserve_region() adds a region to a reserved list so that it doesn't get
turned into device untypeds. init_freemem() also takes a reserved region
list for regions that aren't supposed to be turned into regular untyped
or device untyped. If the ui_p_reg region is > PADDR_TOP then it is
outside of the region of memory that can be turned into regular untyped
and doesn't need to be added to this reserved list, but it still needs
to be added to the device untyped reserved list so that it doesn't show
up as device untyped. (It is already given to user level as frame
objects and so shouldn't also be reachable via different UT objects).
