This functionality is currently unused, and has not been migrated to using DM_I2C, even. Drop this.

- - CONFIG_I2C_ENV_EEPROM_BUS - if you have an Environment on an EEPROM reached over - I2C muxes, you can define here, how to reach this - EEPROM. For example: - - #define CONFIG_I2C_ENV_EEPROM_BUS 1 - EEPROM which holds the environment, is reached over a pca9547 i2c mux with address 0x70, channel 3.
