HID: logitech-dj: add support for the gaming unifying receiver
This receiver is almost identical to the normal unifying ones except: - it is supposed to be paired to only one device (for performance reasons) - the mice reports have a greater ranges in their values, so they are using a different report ID. Tested on a G403 and a G900. Co-authored-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com>
