usb: dwc3: Use clock API to control the memory power states 



GDSC driver is removing control for USB memory power states.
DWC driver need to explicitly call clk_set_flag() API to turn
off both memory core and periphery upon vbus off. When core
clock is turned on both of them will be turn on automatically.
