make legacy ISA probe optional
There are very few ISA drivers left that rely on the static probing from drivers/net/Space.o. Make them all select a new CONFIG_NETDEV_LEGACY_INIT symbol, and drop the entire probe logic when that is disabled. The 9 drivers that are called from Space.c are the same set that calls netdev_boot_setup_check(). Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S. Miller <davem@davemloft.net>
