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

[Hans de Goede <hdegoede@redhat.com>]

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.
