[SCSI] aacraid: add restart adapter platform function
Received from Mark Salyzyn, This patch updates the adapter restart function to deal with some adapters that have specific IOP reset needs. Since the code for restarting the adapter was in two places, changed over to utilizing a platform function in one place.
