The 'choice' statement is primarily used to exclusively select one option, but the 'optional' property allows all entries to be disabled. This feature is rarely used. In fact, it is only used in arch/sh/Kconfig because the equivalent outcome can be achieved by inserting one more entry. The 'optional' property support will be removed from Kconfig. This commit replaces the 'optional' property with a dummy option, CMDLINE_FROM_BOOTLOADER, as seen in some other architectures. Note: The 'default CMDLINE_OVERWRITE' statement does not work as intended in combination with 'optional'. If neither CONFIG_CMDLINE_OVERWRITE nor CONFIG_CMDLINE_EXTEND is specified in a defconfig file, both of them are disabled. This is a bug. To maintain the current behavior, I added CONFIG_CMDLINE_FROM_BOOTLOADER=y to those defconfig files.
