  SVN rev 194378 on 2009-06-17 17:57:52Z by sam
  
  Add workaround to get IXP435 NPE-A working: reseting NPE-A after NPE-C
  causes both to become inoperative; this apparently was done by the original
  IAL code as a workaround for IMEM parity errors which we've not seen so
  just disable the reset.
  
  Note this problem does not occur on IXP425 boards. The linux driver does
  fuse-resets on each NPE but in the order NPE-A < NPE-B < NPE-C (when probing
  for which NPE's are present/operational); we may want to switch to a similar
  scheme but for now disable the resets until we see an issue.
