[U-Boot] [PATCH v2 04/17] SPEAr : Placing ethaddr write and read within CONFIG_CMD_NET

[Vipin KUMAR]

ethaddr can be optionally read from i2c memory. So, chip_config command supports
reading/writing hw mac id into i2c memory. Placing this code within
CONFIG_CMD_NET as this would only be needed when network interface is configured
