[PATCH] convert aic94xx over to using the sas transport end device
Begin introducing the concept of sas remote devices that have an rphy
embedded. The first one (this) is a simple end device. All that an
end device really does is have port mode page parameters contained.
The next and more complex piece will be expander remote devices.
