[SCSI] 3w-9xxx: add MSI support and misc fixes
This patch for the 3w-9xxx scsi driver applies on top of the BKL-pushdown changes in -git9. This patch does the following: - Increase max AENs drained to 256. - Add MSI support and "use_msi" module parameter. - Fix bug in twa_get_param() on 4GB+. - Use pci_resource_len() for ioremap().
