Input: goodix - add upside-down quirk for Teclast X89 tablet
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.
