Without a bool string present, using "# CONFIG_DEVPORT is not set" in
defconfig files would not actually unset devport. This ensured that
/dev/port was always on, but there are reasons a user may wish to disable
it (smaller kernel, attack surface reduction) if it's not being used. Adding
a message here in order to make this user visible.
