ARM: dts: colibri-imx6ull: add touchscreen device nodes
Move all atmel and fusion touchscreen nodes from board-level
to the main module DT. Prepare the DTs for
use with atmel mxt overlays, adding required pinmux groups.
The common scheme of pin groups for TS overlays:
- pinctrl_atmel_conn - SODIMM 106/107 pins for INT/RST (default)
- pinctrl_atmel_adap - SODIMM 28/30 pins for INT/RST signals.
