b43: Module option added to change the GPIO LED mask. This patch exposes the GPIO mask as a module option. This makes it possible to limit the GPIO lines used by the b43 module. Useful for those using the GPIO lines for other things like mmc over GPIO.

It is helpful to those not able / interested in recompiling OpenWRT themselves.
The default action is the same as before, that is 0xf gpiomask.
