rockpro64 rk3399 dwc3 issue

[Shantur Rathore]

Seeing an interesting behaviour.

This NVME to USB disk gets detected 100% of the time when its plugged
in while usb is starting.
So after the usb controller is initialized and ready but before the
controller is scanned for devices.

It seems like the device isn't reset correctly on controller power up
and goes in an error state.
