usb: dwc3: core: Add shutdown support

Browse Source 
The RK3576 platform doesn't use the dwc3 glue layer
which supports to call dwc3_of_simple_shutdown and
dwc3_remove on system shutdown. Therefore, the RK3576
dwc3 controller still keeps working on system shutdown,
and it may cause pending usb irq if usb transmission
happens when do reboot test.

This patch adds shutdown support for RK3576 platform.
