scsi: aacraid: added support for init_struct_8

This  patch lays the groundwork for supporting the new HBA-1000 controller
family.A new INIT structure INIT_STRUCT_8 has been added which allows for a
variable size for MSI-x vectors among other things,  and is used for both
Series-8, HBA-1000 and SmartIOC-2000.
