ARM: dts: colibri-imx6: add atmel mxt device node
Overlays should be as simple as possibles, so return back the node for
the Atmel MXT touchscreen controller.
The common scheme of pingroups for atmel mxt ts:
pinctrl_atmel_conn - uses 107/106 pins for INT/Reset signals;
pinctrl_atmel_adap - uses 28/30 pins for INT/Reset signals.
