drm/radeon: add backlight quirk for hybrid mac

commit 80101790670385a85aca35ecae4b89e3f2fceecc upstream.

Mac laptops with multiple GPUs apparently use the gmux
driver for backlight control.  Don't register a radeon
backlight interface.  We may need to add other pci ids
for other hybrid mac laptops.
