Configure the Type-C and VBUS regulator on PM7250B and wire it up to the
USB PHY, so that USB role and orientation switching works.
For now USB Power Delivery properties are skipped / disabled, so that
the (presumably) bootloader-configured charger doesn't get messed with
and we can charge the phone with at least some amount of power.
