[PATCH net-next 4/4] net: phy: bcm54140: add second PHY ID

From: Michael Walle
Date: Tue Apr 28 2020 - 17:09:14 EST


This PHY have to PHY IDs depending on its mode. Adjust the mask so that
it includes both IDs.

Also move the PHY_ID_BCM54140 out of the brcmphy.h into the driver to
have the mask and the ID in one place.
