The QMP USB3/DP Combo PHY can work in 3 modes:
- DisplayPort Only
- USB3 Only
- USB3 + DisplayPort Combo mode

In order to switch between those modes, the PHY needs to receive
Type-C events, allow marking to the phy with the mode-switch
property in order to allow the PHY to Type-C events.

Perhaps you should be including the usb-switch.yaml schema that's in 
next.
