Log Message:
Kludge to pass bus_space_tag through nvif mappings.

- New `ioctl' NVIF_IOCTL_V0_MAP_NETBSD returns bus_space_tag_t too.
  . Blocked from userland.  (Would only disclose a kernel virtual
    address, so not terribly serious.)
- struct nvif_driver::map function takes bus_sapce_tag, returns
  bus_space_handle in addition to kva pointer.
- struct nvif_driver::unmap function takes bus_space_tag and
  bus_space_handle rather than kva pointer.
- Teach various nvkm object types to return bus space tags too.
- Map them all with BUS_SPACE_MAP_LINEAR so the vaddr works.

XXX The fifo channel might need to be mapped with a subregion.
XXX What to do?
