[SCSI] aacraid: Add Power Management support
For firmware that supports the feature(s), add the ability to start or
stop an array using the associated SCSI commands, to automatically
manage the spin-up of an array on new I/O reporting back the
appropriate check conditions and actions in cooperation with the
normal timeout mechanisms and enable the blackout period management in
the Firmware associated with the background spin-down of the arrays
when the Firmware times out and deems the arrays as idle.
