The mt7628 has an embedded ethernet switch (5 phy ports + 1 cpu port).
Although in IOT mode only port0 is usable, the phy0 is still connected
to the switch, not the ethernet gmac directly.
This patch removes these codes as we should not check only the status of
phy0 because phy0 may not be linked up in router mode which has all 5 phy
ports working.
