dwc3-msm: Move override usb speed functionality outside edev check 



Currently usb speed override functionality doesn't work as expected
when usb role switch based notification is used. Hence move usb speed
override functionality out side edev check within dwc3_resume_work()
API. Also update maximum_speed as max hw supported speed out side
edev check.
