Input: goodix - fix touch coordinates on Cube I15-TC 



[ Upstream commit 1dd5ddc125b4625c3beb8e644ae872445d739bbc ]

The touchscreen on the Cube I15-TC don't match the default display,
with 0,0 touches being reported when touching at the top-right of
the screen.

Add a quirk to invert the x coordinate.
