mainboard/google/puff: Enable net driver on pcie ep 

Let coreboot know there is a NIC device on the end so
that the mac from vpd is set at early boot.

Properly configure the link-leds in devicetree s.t.
valid values are written out to the register at initialization.

BUG=b:146592075,146999042,146999043
BRANCH=none
TEST=Boot to kernel.
     Insert mac address into VPD
       vpd -s ethernet_mac=<address>
     reboot the system.
     Ensure we have ip address and corresponding mac
     address with ifconfig.
     Ensure ethernet controller shows up with lspci.
