Input: goodix - use "inverted_[xy]" flags instead of "rotated_screen"
The goodix touchscreen driver uses a "rotated_screen" flag for systems on which the touchscreen is mounted rotated by 180 degrees with respect to the display. With the addition of support for the dt properties "touchscreen-inverted-x" and "touchscreen-inverted-y", a separate "rotated_screen" flag is not necessary anymore. This patch replaces it by setting the inverted_x and inverted_y flags instead.
