UPSTREAM: rockchip: dts: rk3399-puma: replace 'rockchip, vbus-gpio' with fixed regulator

On the RK3399-Q7, we need to turn on the on-module USB hub before using the
USB host interfaces (only the OTG interface is directly connected to the edge
connector).  This drops the deprecated 'rockchip,vbus-gpio' property and uses
a fixed regulator to turn on the USB hub.
