JFFS2 can be mounted without 'mtdblock' since
a really, really long time. Some git-log
archaeology shows that in 2006 it was possible
to use 'root=' to mount a JFFS2 rootfs:

[MTD] Allow alternate JFFS2 mount variant for root filesystem.
With this patch, "root=mtd3" and "root=mtd:foo" work for a JFFS2 rootfs.
However, there are still plenty of tutorials that mention
mtdblock, so users are still taking this route. Update the Kconfig
to reflect this is no longer needed.
