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.
