arm64: dts: freescale: imx8qm: add apalis eval v1.2 carrier board 



Add support for the new version, v1.2, of Apalis Evaluation Board.
Because only imx8-apalis-eval.dtsi was available and used as the only
board configuration for board version v1.0 and v1.1, it was changed to
be the common hardware configurations for all versions v1.0,
v1.1 and v1.2. Also, two .dtsi board files were added to have the
differences by board. The .dts were organized by SoM and board version.

Board versions v1.0 and v1.1 are compatible with each other and should
use imx8qm-apalis-eval.dts file or imx8qm-apalis-v1.1-eval.dts file
depending on SoM version. Now for v1.2, organized by SoM version too, the
files are imx8qm-apalis-eval-v1.2.dts and imx8qm-apalis-v1.1-eval-v1.2.dts.
