env: eeprom: Remove CONFIG_I2C_ENV_EEPROM_BUS support

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.
