usb: dwc2: gadget: Add remote_wakeup_allowed flag 



It will be set once corresponding set_feature command comes.

True if device is allowed to wake-up host by remote-wakeup
signalling.

This is preparation for remote wake-up support implementation,
it will not be implemented until gadget stack provide interface
for bringing remote wake-up signalling.
