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.
