Do not invalidate the 88410 cache without flushing it first; this is
probably due either to an error in the cpu-to-88410 communication protocol,
or to a bug in the '410 (but since I do not know how to get its revision,
I can't tell whether this is the obscure v1 bug or not).
This allows osiop-connected devices to work correctly on 197SP/DP boards.
