WCL added a c10 phy connected to port B. PTL code is currently
restricting c10 to phy_a only.
PTL doesn't have a PHY connected to PORT B; as such,there will
never be a case where PTL uses PHY B.
WCL uses PORT A and B with the C10 PHY.Reusing the condition
for WCL and extending it for PORT B should not cause any issues
for PTL.
