s390/qeth: make OSN / OSX support configurable
The last machine generation that supports OSN is z13, and OSX is only supported up to z14. Allow users and distros to decide whether they still need support for these device types. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
