It was incorrectly inverted in the device tree as the implementation at the time incorrectly inverted the polarity in its driver, due to a prior device having an inline inverting level shifter. Fix the polarity now while the external display pipeline is incomplete, thereby avoiding any impact to running systems. A matching fix for the driver should be included if this change is backported.
