In the next proposal I shall also add a guard to all DSA drivers, that
if more than one CPU port is set, the driver will not probe.
After that the next patch will try to add multi-CPU support to
mv88e6xxx (while removeing the guard for that driver).
qca8k should also be possible to do, since we used it in such a way in
openwrt. I shall look into that afterwards.
