arm64: dts: rockchip: disable unrouted USB controllers and PHY on RK3399 Puma
[ Upstream commit 3373af1d76bacd054b37f3e10266dd335ce425f8 ]
The u2phy1_host port is the part of the USB PHY1 (namely the
HOST1_DP/DM lanes) which routes directly to the USB2.0 HOST
controller[1]. The other lanes of the PHY are routed to the USB3.0 OTG
controller (dwc3), which we do use.
The HOST1_DP/DM lanes aren't routed on RK3399 Puma so let's simply
disable the USB2.0 controllers and associated part in USB2.0 PHY.
No intended functional change.
