[SCSI] pmcraid: MSI-X support and other changes
1. MSI-X interrupt support 2. Driver changes to support new maxRAID controller FW version. The changes are mainly done to handle async notification changes done in newer controller FW version. 3. Added state change notifications to notify applications of controller states.
