Log Message:
Allow nvkm_client_map to map subregions.

Linux ioremap does not care about overlapping mapped regions, but
bus_space_map does.  Since nouveau ioremaps the entire register space
of BAR 0, and separately some subregions of it, we need to convey the
bus addresses in question to it in order to bus_space_subregion.

Kinda kludgey, but we don't care about running this in userland or
anything.

While here: initialize object->map.tag.  Not physically necessary on
x86 as long as the x86_io_mem_tag is nonull, so this won't fix any
symptoms on x86, but it is wrong to leave it null.
