Marek Vasut 2f96064d0c arm64: dts: imx8mp: Describe M24C32-D write-lockable page in DH i.MX8MP DHCOM DT
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.
