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. The correct way to handle this will be through a
usb-connector node, but for now we'll just mark the regulator as
always-on so that it will be enabled automatically during boot.
