[PATCH] arm64: dts: rdu3: add UCS1002 charge controller node

[Lucas Stach]

Add the charge controller node. With the controller driver loaded
the VBUS of the user USB socket is controlled exclusively via i2c
with the GPIO controls ignored, so vbus-supply for the user USB
port must be linked to the charge controller.

Hog the previously used GPIO control to unconditionally enable
VBUS until the driver is loaded.
