sh: Remove superhyway bus support

The superhyway bus driver was only referenced on SH4-202, which is now gone,
so remove it all as well.

I could find no trace of anything ever calling superhyway_register_driver(),
not in the git history but also not on the web, so I assume this has never
served any purpose on mainline kernels.
