Cleanup some AEN severity levels.
1.02.00.027 - Add drive not supported AEN code for SATA controllers.
Remove spurious unknown ioctl error message.
1.02.00.028 - Fix bug where multiple controllers with no units were the
same card number.
Fix bug where cards were being shut down more than once.
1.02.00.029 - Add missing pci_free_consistent() in tw_allocate_memory().
Replace pci_map_single() with pci_map_page() for highmem.
Check for tw_setfeature() failure.
1.02.00.030 - Make driver 64-bit clean.
1.02.00.031 - Cleanup polling timeouts/routines in several places.
Add support for mode sense opcode.
Add support for cache mode page.
Add support for synchronize cache opcode.
