usb: dwc2: Add exit partial power down when port is resumed
Added flow of exiting Partial Power Down in
"dwc2_port_resume()" function when core receives resume.
NOTE: Switch case statement is used for hibernation partial
power down and clock gating mode determination. In this patch
only Partial Power Down is implemented the Hibernation and
clock gating implementations are planned to be added.
