The 'choice' statement is primarily used to exclusively select one option, but the 'optional' property allows all entries to be disabled. This feature is only used in arch/sh/Kconfig because the equivalent outcome can be achieved by inserting one more entry as a place-holder. This approach is commonly used, for example, LTO_NONE, DEBUG_INFO_NONE, INITRAMFS_COMPRESSION_NONE, etc. The 'optional' property support will be removed from Kconfig. This commit converts the last user. Note: The 'default CMDLINE_OVERWRITE' statement does not work as intended in combination with 'optional'. If neither CONFIG_CMDLINE_OVERWRITE nor CONFIG_CMD_EXTEND is specified in a defconfig file, both of them are disabled. This is a bug. To maintain the current behavior, I added CONFIG_CMD_NO_MODIFY=y to those defconfig files.
