net: drop !NET_MULTI bcm570x/tigon3 drivers
These drivers have never been converted to NET_MULTI, and they are only
used by one board (BMW). So drop the drivers until someone feels like
rewriting them for NET_MULTI support.
Rather than punting the BMW board completely, just disable net support
in its board config. Seems to build fine without it.
