Subject: [PATCH] arm64: dts: fsl: Specify phy-mode for CPU ports
PHYLINK requires that device tree nodes have a phy-mode or
phy-connection-type property. The internal Felix ports really are
connected to the ENETC via 2 back-to-back MACs, so the correct MII type
is GMII (one of which is overclocked at 2.5Gbaud, but still GMII).
