There is a series for this [1] that Dmitry seems to have no time to pick
up for a long while now, which we carry downstream. Without correct
touchkey definition the touch controller reassigns the tkey lanes to the
screen surface and display calibration breaks a bit, but since we don't
have the changes upstream for now, probably want to drop this line from
the submission so we don't introduce more dtbs_check warnings.
