HID: usbhid: Implement may_wakeup ll-driver callback
Without a ll-driver callback hid_hw_may_wakeup() will return: device_may_wakeup(hdev->dev.parent), usb_hid_driver instantiated hid devices have their parent set to the usb-interface to which the usb_hid_driver is bound, but the power/wakeup* sysfs attributes are part of the usb-device. Add a may_wakeup ll-driver callback which calls device_may_wakeup() on the usb-device instead.
