[PATCH 06/10] usb: dwc3: add 'saved_state' field to dwc3_ep structure

[Felipe Balbi <balbi@xxxxxx>]

From: Paul Zimmerman <Paul.Zimmerman@xxxxxxxxxxxx>

This extra field will save endpoint state when we're
about to enter hibernation. It will be used later
to restore the endpoint state when resuming.
