[PATCH v1 6/6] usb: dwc3: core: Notify USB3 PHY as well for DRD modes

[Manu Gautam]

Driver currently notifies only USB3 PHY for mode change.
Extend this to USB3 PHY so that driver based on the mode
can release system resources - clocks, regulators etc.
and can even turn off PHY during runtime suspend.
