The ili9882t touch screen chip same as Elan eKTH6915 controller
has a reset gpio. The difference is that ili9882t needs to use
vccio-supply instead of vcc33-supply. Doug's series[1] allows panels
and touchscreens to power on/off together, let's add a phandle for this.

It's v6 but this still misses the changelog.

Best regards,
