ARM: dts: imx6qdl-dhcom: Identify the PHY by ethernet-phy-id0007.c0f0

Identify the PHY by its compatible ID value. In some cases during
boot, the PHY needs to be reset to be accessible, but this is only
possible if the PHY is recognized. In that case, the automatic
detection of the PHY does not work and a static compatible ID
value is need.
