[PATCH] HID: multitouch: Fix GeneralTouch products and add more PIDs

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

From: Luosong <android@generaltouch.com>

GeneralTouch products should use the quirk SLOT_IS_CONTACTID
instead of SLOT_IS_CONTACTNUMBER.

Adding PIDs 0101,e100,0102,0106,010a from the new products.

Tested on new and older products by GeneralTouch engineers.

Hi Luosong,

I took the liberty to rewrite the commit message for it to be
more compliant with the kernel rules:
- there should be a one line title commit message first,
- and the rest should detail the patch, tell how it was tested, etc...

If you could just give our ack on this one, Jiri would be able to take it
through his tree.

Cheers,
Benjamin
