[SCSI] aacraid: Add Power Management support

Browse Source 
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.
