Subject: [PATCH net-next v3 02/12] net: dsa: lantiq_gswip: Only allow phy-mode = "internal" on the CPU port

From: Martin Blumenstingl <martin.blumenstingl@...glemail.com>

Add the CPU port to gswip_xrx200_phylink_get_caps() and
gswip_xrx300_phylink_get_caps(). It connects through a SoC-internal bus,
so the only allowed phy-mode is PHY_INTERFACE_MODE_INTERNAL.
