usb: dwc2: Move exit hibernation to dwc2_port_resume() function 

This move is done to call hibernation exit handler in
"dwc2_port_resume()" function when core receives port resume.
Otherwise it could be confusing to exit hibernation in
"dwc2_hcd_hub_control()" function but other power saving modes
in "dwc2_port_resume()" function.
