ARM: dts: colibri-imx6: rearrange PCAP device nodes
Capacitive TS controllers are parts of peripheral, not boards.
Move all related stuff 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 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.
