drivers/net/r8168: Add support for Realtek RT8125

The Realtek RT8168 and RT8125 have a similar programming interface,
therefore add the PCI device ID for the RT8125 into driver for support.

BUG=b:193750191
TEST=emerge-brask coreboot chromeos-bootimage. Test on brask whose NIC
     is RT8125. Check if the default MAC is written into the NIC.
