This series adds support for Surface Pen devices to the Surface 3
touchscreen input driver.

This series works with both styles of pen:
the old style with pressure sensitive tip, an eraser button, and a
secondary input button, as well as the new style pen which does not
have a dedicated eraser button.

The top button on the pen is not supported by this patch. Those
buttons are a separate Bluetooth device.
