This allows the OS to power sequence the touchscreen more properly. For the most part, this is just expected to marginally improve power consumption while the screen is off. However, in at least one trogdor model (wormdingler) it's suspected that this will fix some behavorial corner cases when the panel power cycles (like for a modeset) without the touchscreen power cycling. NOTE: some trogdor variants use touchscreens that don't (yet) support linking the touchscreen and the panel. Those variants are left alone.
