net: dsa: mv88e6xxx: accept phy-mode = "internal" for internal PHY ports

Browse Source 
The ethernet-controller dt-schema, mostly pushed forward by Linux, has
the "internal" PHY mode for denoting MAC connections to an internal PHY.

U-Boot may provide device tree blobs where this phy-mode is specified,
so make the Linux driver accept them.

It appears that the current behavior with phy-mode = "internal" was
introduced when mv88e6xxx started reporting supported_interfaces to
phylink. Prior to that, I don't think it would have any issues accepting
this phy-mode.
