Subject: [PATCH] arm64: dts: rockchip: fix u2phy1_host status for NanoPi R4S

The u2phy1_host should always have the same status as usb_host1_ehci
and usb_host1_ohci, otherwise the EHCI and OHCI drivers may be
initialized for a disabled usb port.

Per the NanoPi R4S schematic, the phy-supply for u2phy1_host is set to
the vdd_5v regulator.
