sky2: fix LED management
Fix problems in LED management, so ethtool -p works correctly on Yukon-EC and other chips. The driver was incorrectly setting the PHY LED overide bits. Moral: read the spec sheet, not the vendor driver. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
