To be honest, we may just want to remove this API. A driver that requires a zero
sized MMIO region with only optional runtime derived access offsets seems a bit
too exotic.
That doesn't mean that occasionally we'll have drivers needing runtime offsets,
so eventually we want to support that with the register!() macro, but it's not
*that* urgent.
