[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.
