Subject: [PATCH v2 0/2] kconfig: remove unneeded 'optional' property support


Kconfig support 'optional' for choice blocks, but it is unneeded.

Currently, it is only used in arch/sh/Kconfig.

Covert it (add a place-holder option, CONFIG_CMDLINE_NO_MODIFY) and
clean up the Kconfig code.

(Ack from the sh maintainer is appreciated)
