This fixes usage of backlight control
As GMUX depends on IO for iGP to be enabled and active, lock the IO at
vgaarb level. This should prevent GPU driver for dGPU to disable IO for
iGP while it tries to own legacy VGA IO.
This fixes usage of backlight control combined with closed nvidia
driver on some Apple dual-GPU (intel/nvidia)
