The following patch adds struct megasas_instance_template changes to
the megaraid_sas driver, and changes all code to use the new instance
entries:

   irqreturn_t (*service_isr )(int irq, void *devp);
   void (*tasklet)(unsigned long);
   u32 (*init_adapter)(struct megasas_instance *);
   u32 (*build_and_issue_cmd) (struct megasas_instance *, struct scsi_cmnd *);
   void (*issue_dcmd) (struct megasas_instance *instance,
                              struct megasas_cmd *cmd);
