  SVN rev 224270 on 2011-07-22 16:37:04Z by mav
  
   - Use mutex to serialize index/data register pair usage, when
  accessing SATA registers. Unserialized access under heavy load caused
  wrong speed reporting and potentially could cause device loss.
   - To free memory and other resources (including above), allocated
  during chipinit() method call on attach, add new chipdeinit() method,
  called during driver detach.
