Right now yes, but the GPIO serves to switching between SLPI and AP mode at
runtime, see [1]
The driver lack supports for SLPI, but at moment when SLPI support lands, we
should be able do something like:
-> device starts, touchscreen works
-> screen goes to sleep, but instead of powering off touchscreen, it switches to
SLPI mode
-> user taps at touchscreen, device wakes up
Thus I think we need to support this GPIO in the driver.
