[ES40-developers] Patch: scsi page code 0

[Brian W. <bdw...@in...>]

Tru64 needed scsi page code 0 for it to boot up properly, so here's a
patch that adds it.  Its basically a list of page codes supported, so if
any others are added, make sure to insert them in the proper place in
page 0's list and increase the page length.
