Subject: [PATCH 4.4 057/162] Input: goodix - add upside-down quirk for Teclast X89 tablet

From: Hans de Goede <hdegoede@...hat.com>

commit df5b5e555b356662a5e4a23c6774fdfce8547d54 upstream.

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.
