usb: dwc2: gadget: Fix enter to hibernation for UTMI+ PHY

For UTMI+ PHY, according to programming guide, first should be set
PMUACTV bit then STOPPCLK bit. Otherwise, when the device issues
Remote Wakeup, then host notices disconnect instead.
For ULPI PHY, above mentioned bits must be set in reversed order:
STOPPCLK then PMUACTV.
