arm64: dts: rockchip: and phy node for rk3368 usb otg

Browse Source 
The usb otg doesn't need phy node, because it uses
legacy controller driver "dwc_otg_310". But the phy
node is needed for uboot which uses kernel dtb. And
it's also useful for otg controller driver if we
switch to dwc2 driver later.
