[ Upstream commit 7d87ed70fc95482c12edf9493c249b6413be485e ]

The touchscreen on the SUPI S10 tablet reports inverted Y coordinates,
causing touch input to be mirrored vertically relative to the display.

Add a quirk to set the "touchscreen-inverted-y" boolean device-property
on the touchscreen device, so that the goodix_ts driver will fixup
the coordinates.
