	drivers/misc/i2c_eeprom.c fails to build unless CONFIG_FIT_SIGNATURE
is defined.

By the way, Sandbox (enabling CONFIG_FIT_SIGNATURE) is luckily
working depending on it.
Sandbox includes include/asm-generic/errno.h
            from include/errno.h
            from include/u-boot/rsa-checksum.h
            from include/image.h
            from include/common.h
            from drivers/misc/i2c_eeprom.c
