ar71xx: Set eth1 MAC address from EEPROM for WNDR3700

The WNDR3700's art/caldata partition contains three MAC addresses at
offsets 0, 6, and 12, used for eth0/wlan0 (shared), eth1, and wlan1,
respectively. The existing code configures eth1's MAC address by adding
1 to eth0's instead of using the value stored in the EEPROM. This patch
causes the stored value to be used directly. (On my WNDR3700s, the three
stored addresses are all sequential anyway.)
