Tf101 touch extension

Created by: LongnoseRob

This adds the data for the touchscreen to the device-asus-tf101 package.

this is still WIP, as the touchscreen device gets detected, but ther is something wrong.

The touchscreen does not work in weston or in xfce4. I have some more details from the Xorg.0.log after installing xfce4:

[ 691.457] (II) config/udev: Adding input device mxt1386 (/dev/input/event0)

[ 691.458] (**) mxt1386: Applying InputClass "libinput touchscreen catchall"

[ 691.764] (II) This device may have been added with another device file.

Does anybod know what this Kernel error message means in detail? Could it be that my touchscreen calibration data is wrong? Could we get the touch-screen calibraton data somehow on the shell from TWRP?

Other thing I have tested sofar: -USB support for mouse/keyboard works -dock keyboard works, -dock touchpad does not work -wifi misses firmware
