mb/google/brya/var/agah: Remove stop pin declaration for LAN 

Currently, the system fails to enter S0ix as the stop pin declation
for LAN device will prevent system from entering suspend.
So remove the stop pin declaration.

Also add device_index=0 for the first NIC to get correct MAC
from VPD setting.

BUG=b:210970640
TEST=Build and suspend_stress_test -c 20 pass
     Check LAN works fine after resume
