Input: elantech - force needed quirks on Fujitsu H760

commit f9a703a54d16ba2470391c4b12236ee56591d50c upstream.

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.
