mb/google/rex/variants/ovis: Use and configure RT8168 driver

This makes sure google/ovis don't get a random mac address on boot.

Additionally, program the LAN WAKE GPIO properly as per the Ovis
schematics dated July'23.

BUG=b:293905992
TEST=Verified on google/ovis that able to get the fixed MAC address across the power cycles.
