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 as a place-holder.

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.

Changes in v2:
- Rename CONFIG_CMDLINE_NO_MODIFY to CONFIG_CMDLINE_FROM_BOOTLOADER
- Capitalize the first work of the subject
