arm64: dts: rockchip: rk3568: add quirk-skip-phy-init for usb otg0

The rk3568 usb dwc3 controller has phy management at its
own driver to cover both device and host mode. And for
usb otg0, it enable device wakeup that make the usb hcd
core to keep the phy initialized so the device can wake
up the system. However, most of rk3568 platforms power
off the logic and cause phy grf lost power, thus we need
to add quirk-skip-phy-init to reinit phy grf upon system
resume.
