Subject: Input: goodix - add upside-down quirk for Teclast X89 tablet
Git-commit: df5b5e555b356662a5e4a23c6774fdfce8547d54
Patch-mainline: 5.5-rc1
References: bnc#1151927 5.3.16
The touchscreen on the Teclast X89 is mounted upside down in relation to
the display orientation (the touchscreen itself is mounted upright, but the
display is mounted upside-down). Add a quirk for this so that we send
coordinates which match the display orientation.
