Subject: [PATCH] Input: goodix - add upside-down quirk for Teclast X89 tablet

Git-commit: df5b5e555b356662a5e4a23c6774fdfce8547d54

Patch-mainline: v5.5-rc1

References: bsc#1051510

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.
