ARM: dts: apalis/colibri-imx6: Add support for v1.2

Apalis/Colibri iMX6 V1.2 replaced the STMPE811 ADC/touch controller,
which is EOL, with the TLA2024 ADC and AD7879 touch controller.

Accurately describe the new hardware.

v1.1 of these SoMs is still described by the following DTSI files:
imx6qdl-apalis.dtsi
imx6qdl-colibri.dtsi

v1.2 is now supported by a DTSI that modifies v1.1:
imx6qdl-apalis-v1.2.dtsi
imx6qdl-colibri-v1.2.dtsi

For each carrier board using these modules, a new DTS file was added
that includes the v1.1 DTS and modifies it with this v1.2 DTSI.

The original DTS can be used for modules up to and including v1.1.
