When allocating virtual space for bus_space_map, don't use
uvm_km_alloc() (which allocates some virtual space and then
$size_of_mapping pages which it then enters) *then* pmap_kenter the
bus_space address that we wish to map, it's just a little bit stupid and
a waste of memory.
replace with uvm_km_valloc and ponies for everyone.
