Philippe Schenker 24ffaa23ce ARM: dts: imx6-apalis: Add touchscreens used on Toradex eval boards
This commit adds the touchscreen from Toradex so one can enable it.
It is disabled by default because the pins are also used for PWM<B>,
PWM<C>, aka pwm2, pwm3 which is the standard use for colibri boards.
