sky2: Yukon Extreme support
This is basic support for the new Yukon Extreme chip, extracted from the new vendor driver 10.0.4.3. Since this is untested hardware, it has a big fat warning for now. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
