[PATCH] HID: multitouch: add FocalTech FTxxxx support

[Benjamin Tissoires <benjamin.tissoires@redhat.com>]

This is a Win7 device which does not work correctly with the default
settings (not the previous default BT).
However, the quirk ALWAYS_TRUE makes it working like a charm.

Hi Jiri,

well, it's been a long time since I did not add those kind of small patches.
And I really hope not having to do some gain soon :)

Cheers,
Benjamin
