[PATCH 10/13] dts: sdm845-db845c: add u-boot fixups

The USB VBUS supply for the type-A port is enabled via a GPIO regulator.
This is incorrectly modelled in Linux where only the PCIe dependency is
expressed. Add a U-Boot specific dtsi snippet so that this supply will
get enabled when initialising USB.
