AHCI - Improve hot-plug sequencing.
* Properly either fail or restart outstanding commands when we get a PCS
interrupt, based on the event we determined to have occurred.
NOTE: A PCS event stops command processing, so at the very least command
processing must be restarted by cycling the port.
* Reset the port's ap->ap_state when a hotplug-insertion is detected, so
the port has a chance to get out of its failed state.
