platform/x86: asus-wmi: add support for Vivobook GPU MUX
Add support for the Vivobook dgpu MUX available on the ASUS Viviobook
and some of the other ranges (Zen).
This MUX functions exactly the same as the existing ROG MUX support so
the existing functionality now detects which MUX is available and uses
that for control.
