[Nouveau] [PATCH v2 2/2] nouveau/bl: Do not register interface if Apple GMUX detected
The Apple GMUX is the one managing the backlight, so there is no need for
Nouveau to register its own backlight interface.
v2: Do not split information message on two lines as it prevents from grepping
it, as pointed out by Hans de Goede
