axnet_cs: fix phy_id detection for bogus Asix chip.
axnet_cs: (1) Some Asix phy return bogus value except 0 or 0xffff. Skip this phy_id. (2) Some Asix chip need to set "select Internal PHY" bit at AX88190_init. Signed-off-by: Ken Kawasaki <ken_kawasaki@spring.nifty.jp> Signed-off-by: David S. Miller <davem@davemloft.net>
