[PATCH v3 24/32] Add a new Kconfig for command-line entry

[Simon Glass]

At present EXPO requires CMDLINE since it uses cli_readline, which is
enabled by CMDLINE. It should be possible to enter lines of text to an
expo without having CMDLINE available.

Fix this dependency by creating a new Kconfig for cli_readline
