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

I believe you mentioned that the MP controller is host-only
by design. If that's true, move this property to the SoC dtsi
and leave an appropriate comment.

Hi Konrad,

  Yes, it is host only controller. We can move this to sc8280xp.dtsi but 
wanted to keep uniformity, so made the change here. I can move it to 
base DT.
