[PATCH] Input: goodix - Add upside-down quirk for Teclast X98 Pro tablet

["Simon Beginn" <linux@xxxxxxxxxxxxx>]

The touchscreen on the Teclast x98 Pro is also mounted upside-down in relation to the display orientation. I added it also to the list of those devices. Verified it works on my device - this has not been tested with more users than myself...
