[PATCH 4/4] arm64: dts: allwinner: h700: Add USB Host for RG35XX-H

[Chris Morgan <macroalpha82@gmail.com>]

From: Chris Morgan <macromorgan@hotmail.com>

The RG35XX-H has a USB host port in addition to the USB OTG port used
for charging. The host port receives its power from two distinct GPIO
controlled regulators.
