Hi,
This patch adds Goodix GT7868Q device support to hid-multitouch.
The device is used on Lenovo ThinkBook 13x Gen 4 series of laptops
and have incorrect descriptor that hid-parse fails to parse
hence device is not working.

Terry Wong made a driver (fixup) that uses report_fixup to correct
the values in the descriptor. This is mostly re-using hid-multitouch
code. With his permission, I added the fixup to the driver itself.

Open to the feedback if there's a better approach to solving
the issue.
