platform/x86: asus-wmi: Support the hardware GPU MUX on some laptops
Support the hardware GPU MUX switch available on some models. This
switch can toggle the MUX between:
- 0, Dedicated mode
- 1, Optimus mode
Optimus mode is the regular iGPU + dGPU available, while dedicated
mode switches the system to have only the dGPU available.
