dt-bindings: arm: fsl: Add toradex,apalis_imx6q-eval-v1.2 board

Add the toradex,apalis_imx6q-eval-v1.2 compatible string for version 1.2
of the Apalis Evaluation Board.

Version v1.2 includes the following changes compared to v1.1:

- 8-bit MMC connector replaced with a 4-bit uSD connector.
- Audio codec NAU88C22 added.
- M24C02 EEPROM i2c added.
- MIPI-CSI-2 connector directly to the board added.
- PCIe switch PEX8605 removed and PCIe now is routed directly to Mini
  PCIe connector.
- Power measurement IC INA219 added.
- Replaced DVI with HDMI connector.
- Single-channel USB to UART converter replaced with four-channel USB
  to UART/JTAG.
- Temperature sensor TMP75 added.

Please note that version v1.0 (which reached EOL) is compatible with
v1.1, therefore toradex,apalis_imx6q-eval compatible string should be
used for both v1.0 and v1.1.
