The current imx8mp-dhcom-som.dtsi describes prototype rev.100 SoM,
update the DT to describe production rev.200 SoM which brings the
following changes:
- Fast SoC GPIOs exposed on the SoM edge connector
- Slow GPIOs like component resets moved to I2C GPIO expander
- ADC upgraded from TLA2024 to ADS1015 with conversion interrupt
- EEPROM size increased from 256 B to 4 kiB
