[AVR32] Initialize phy_mask for both macb devices
The STK1000 uses pullups on the MDIO lines to the PHY, but they are too weak. This causes the PHY layer to detect PHYs on all possible MII addresses. Mask out all but the correct address to prevent this from happening. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
