-Required properties:
-- compatible: should be "hisilicon,hi3670-usb-phy"
-- #phy-cells: must be 0
-- hisilicon,pericrg-syscon: phandle of syscon used to control phy.
-- hisilicon,pctrl-syscon: phandle of syscon used to control phy.
-- hisilicon,sctrl-syscon: phandle of syscon used to control phy.
-- hisilicon,usb31-misc-syscon: phandle of syscon used to control phy.
-- eye-diagram-param: parameter set for phy
-- usb3-phy-tx-vboost-lvl: parameter set for phy
-Refer to phy/phy-bindings.txt for the generic PHY binding properties
