ar8216: use genphy_config_aneg also for PHY 0

Browse source 
Kernel 3.14 introduced a switch reset in phy_init_hw in drivers/net/phy
causing BMCR_ANENABLE to get cleared.

Due to the fact that ar8xxx_phy_config_aneg does nothing for
PHY 0 autonegatiation support remains disabled.
This can cause ports to operate at 10MBit/half-duplex only.

Fix this by calling genphy_config_aneg for PHY 0 too as
genphy_config_aneg sets BMCR_ANENABLE if it's not yet set.
Fixes: ticket 17800
