The i.MX8MP DHCOM SoM production rev.200 is populated with M24C32-D EEPROMs which have Additional Write lockable page at separate I2C address. Describe the page in DT to make it available. Disable the additional page in rev.100 SoM DTO as those devices contain EEPROM without an Additional Write lockable page. Signed-off-by: Marek Vasut <marex@denx.de>
