In pmap_mapdev(), if the physical memory range is not covered by an EFI
memory descriptor, don't return NULL as the virtual address, return the
direct-mapped uncacheable virtual address for it. At first, this was
needed only for the Altix 350, but now even some high-end HP machines
have devices mapped to physical addresses that aren't covered by the
EFI memory map.
