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.
