With other probing issues out of the way (by marking LCD_1V8 always on)
it turns out we can't use either touch or DSI until we pulled both RESX
and TP_RSTN¹ so instead of guessing wait until the panel is up.

This replaces one hack (probe defers) by another (more reliable) one.

¹) This appeared to be otherwise since even a failed probe of the touch
controller (happening way too early before avdd/avee are up) is enough
and thaat only became appearend when not loading the touch controller
module at all.
