This is a restructure of the IPMI driver, mostly to remove SRCU. The
locking had issues, and they were not going to be straightforward to
fix. Plus it used tons of memory and was generally a pain.
Most of this moves handling of messages out of bh and interrupt context
and runs it in thread context. Then getting rid of SRCU is easy.
This also has a minor cleanup to remove a warning on newer GCCs and to
fix some documentation.
