Subject: [PATCH] hid: usb: Add device quirks for Freeway Airmouse T3
 and MX3

These wireless mouse/keyboard combo remote control devices specify
multiple "wheel" events in their report descriptors. The wheel events
are incorrectly defined and apparently map to accelerometer data, leading
to spurious mouse scroll events being generated at an extreme rate when
the device is moved.

As a workaround, use HID_QUIRK_INCREMENT_USAGE_ON_DUPLICATE to mask
feeding the extra wheel events to the input subsystem.

See: https://github.com/raspberrypi/firmware/issues/1189
