Input: atmel_mxt_ts - add touchpad button mapping for Samsung Chromebook Pro

commit f372b81101e6895252298e563d634d5e44ae81e7 upstream.

This patch adds the correct platform data information for the Caroline
Chromebook, so that the mouse button does not get stuck in pressed state
after the first click.

The Samus button keymap and platform data definition are the correct
ones for Caroline, so they have been reused here.
