ARM: dts: imx: Add DT overlays for DH i.MX6 DHCOM SoM and boards

Add DT overlays to support DH i.MX6 DHCOM SoM carrier board expansion
modules. The following DT overlays are implemented:
- PDK2:
  - DH 497-200 Display board in edge connector X12
  - DH 505-200 Display board in edge connector X12
  - DH 531-100 SPI/I2C board in header X21
  - DH 531-200 SPI/I2C board in header X22
  - DH 560-200 Display board in edge connector X12
- PicoITX:
  - DH 626-100 Display board in edge connector X2
