[PATCH 3/3] Input: joydev - ignore accelerometer devices

From: Roderick Colenbrander <roderick.colenbrander@sony.com>

Gamepads like DualShock 3 / 4 as of 4.12 started reporting motion
sensors on a separate evdev node. Joydev is picking these devices
up as well, but they don't make sense for the joydev interface.
