HID: logitech-dj: Implement may_wakeup ll-driver callback
Without a ll-driver callback hid_hw_may_wakeup() will return:
device_may_wakeup(hdev->dev.parent), but for the hid devices
instantiated by logitech-dj for devices behind the receiver the
logitech-dj hid(pp)-device is the parent.
Add a logi_dj_ll_may_wakeup() callback which calls hid_hw_may_wakeup()
on the logitech-dj hid(pp) parent-hid-device.
