Add a new Kconfig option EEPROM_LAYOUT_VERSIONS, and hide eeprom layout versionsing code behind it. Only print the relevant help in 'eeprom' command usage if this option is enabled.
Enable this new option for cm_fx6_defconfig and cm_t43_defconfig. These are the only boards using EEPROM layout versioning.
