cmd_eeprom: I2C updates
- CONFIG_ENV_EEPROM_IS_ON_I2C
define this, if you have I2C and SPI activated, and your
EEPROM, which holds the environment, is on the I2C bus.
- CONFIG_I2C_ENV_EEPROM_BUS
if you have an Environment on an EEPROM reached over
I2C muxes, you can now define, how to reach this
EEPROM.
