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
