HID: logitech-dj: Fix Dinovo Mini when paired with a MX5x00 receiver
Some users are pairing the Dinovo keyboards with the MX5000 or MX5500 receivers, instead of with the Dinovo receivers. The receivers are mostly the same (and the air protocol obviously is compatible) but currently the Dinovo receivers are handled by hid-lg.c while the MX5x00 receivers are handled by logitech-dj.c. When using a Dinovo keyboard, with its builtin touchpad, through logitech-dj.c then the touchpad stops working because when asking the receiver for paired devices, we get only 1 paired device with a device_type of REPORT_TYPE_KEYBOARD. And since we don't see a paired mouse, we have nowhere to send mouse-events to, so we drop them. Extend the existing fix for the Dinovo Edge for this to also cover the Dinovo Mini keyboard and also add a mapping to logitech-hidpp for the Media key on the Dinovo Mini, so that that keeps working too.
