Enable tertiary controller for SA8295P (based on SC8280XP).
Add pinctrl support for usb ports to provide VBUS to connected peripherals.

These are not just pinctrl entries. They hide VBUS regulators. Please
implement them properly as corresponding vbus regulators.


Hi Dmitry. Apologies, can you elaborate on your comment. I thought this implementation was fine as Konrad reviewed it in v13 [1]. I removed his RB tag as I made one change of dropping "_state" in labels.
