mb/google/rex/variants/ovis: Use correct device_index for RT8168

Fix ethernet MAC address configuration. Currently, coreboot would
use ethernet_mac0 for both ports when setting the system's MAC
address. Instead, set the right device_index for the second controller
to pick up ethernet_mac1.

BUG=b:294856127
TEST=boot device and observe two different MAC addresses on the ethernet
     ports.
