kernel - AHCI - enable AHCI device initiated power management

* Add hw.ahci sysctls to allow the power management state to be set and
  monitored.

* Issue device features command when aggressive power management is
  enabled to turn on device-initiated power management, and turn it off
  when power management is set to none.

* Currently does not try do power management for devices behind a
  PM.
