b44: Set PHY address to NO_PHY if reset fails.
Do a PHY reset to test if there is an active phy and set the PHY address to B44_PHY_ADDR_NO_PHY in case of an not active phy. This is needed for the Linksys WRTSL54GS and Asus WL-500W. This patch was used in OpenWRT for a long time. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: David S. Miller <davem@davemloft.net>
