Uses nuvoton,sys phandle and HUSBH0_GATE clock per the binding. - usb (DWC2 gadget, USB0): phys = <&usb_phy 0>, dr_mode = peripheral. - ehci0/ohci0 (USB0 host): phys = <&usb_phy 0>, companion pairing. - ehci1/ohci1 (USB1 host): phys = <&usb_phy 1>. Board files (ma35d1-som-256m.dts, ma35d1-iot-512m.dts) add pinctrl for VBUSVLD, PWREN and OVC signals and enable all USB nodes.
