Just like Fujitsu CELSIUS H730, the H760 also has an Elantech touchpad
with the same quirks. Without this patch, the touchpad is useless
out-of-the-box as the mouse pointer won't move.
This patch makes the driver aware of both the crc_enabled=1
requirement and the middle button, making the touchpad fully
functional out-of-the-box.

This patch will also apply without changes to older kernel versions:
I made this originally on 4.4.19 and am currently using it on
my work laptop with 4.4.22.
Backporting to any version that includes commit
f386474e12a560e005ec7899e78f51f6bdc3cf41 should be trivial.

Applied and marked for stable, thank you.
