What I had in mind when I created the new port operation "enable_pm"
was that other controllers (besides the ahci controller) could define their
own method of enabling power management.  Maybe for non-ahci controllers this
is a software based solution which uses generic SATA dipm/hipm stuff and 
polling.  

See patch 2/3 of this series for the implementation of this.
