i965: Move hardware limits to brw_device_info.
Since each kind of device has its own brw_device_info structure, we can simply store the URB and thread limits there. This eliminates all the large if-ladders, and simplifies the context initialization code quite a bit. Signed-off-by: Kenneth Graunke <kenneth@whitecape.org>
