HID: hid-mosart: ignore buttons report
This commit allows the device to be recognized as a touchscreen, and not a touchpad by xf86-input-evdev. The device has 2 modes. The first one is an emulation of a touchscreen by sending left and right button, and the second mode is the one used in dual-touch (sending trackingID, touch and else). That's why there is a hid report containing left and right buttons (9000001 and 9000002). The point is that xorg relies on these fields to determine if it's a touchpad or a touchscreen. Clearing the report (return -1) makes xorg detecting it out of the box as a quite pleasant (dual)touchscreen.
