All other EC drivers were added lately without proper review. That they skip
sanity checks (and documentation too), is the foremost reason why I'm currently
holding a release back. The situation of the superio probing is bad indeed, but
not as bad as starting with EC RAM writes. The comment in probe_superio() proves
the point. IMHO, we should only probe for expected chips, `board_enable` provides
the infrastructure for it.

Patches (also to clean up the superio situation) are welcome of course.
