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

Browse Source 
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
