usb: dwc3: rockchip: add pm runtime control for dwc3 parent

In usb3 tcphy init, it will access usb3 module to set
usb3 working on USB3.0 mode or USB2.0 only mode, and
usb3 pd must be enabled before do this operation. So
we add pm runtime control for dwc3 parent in extcon
evt work. If plug in usb device, resume dwc3 parent
first to enable usb3 pd and then do phy init.
