Mike Smith 9eee27f16d Updates resulting from new documentation from Mylex and some cleaning: 
- Don't keep private copies of some of the data fields from the
   ENQUIRY and ENQUIRY2 commands.  Instead, standardise on the ENQUIRY2
   command for initial adapter information, and keep a copy of the entire
   structure.  Refer to it where appropriate.

 - Move all of the controller description functionality into a new
   function.  Print lots more controller data if bootverbose is set.
   Add knowledge of the DAC960 PR, PT, PTL0 and PRL controllers, rename
   the 960PTL -> PTL0 and 1100P -> 1100PVX.

 - Correctly terminate an error message.

The controller interface procedures have been reviewed against the
Mylex-supplied documentation; no changes appear necessary at this
time.
