[PATCH v4 3/3] usb: dwc3: core: Suspend PHYs on runtime suspend in host mode

Some PHY drivers (e.g. for Qualcomm QUSB2 and QMP PHYs) support runtime PM to reduce PHY power consumption during bus_suspend. Add changes to let core auto-suspend PHYs on host bus-suspend using GUSB2PHYCFG register if needed for a platform. Also perform PHYs runtime suspend/resume and let
