Subject: [PATCH net-next 5/5] dts: qcom: ipq4019: Add description for the IPQ4019 ESS EDMA and switch

The Qualcomm IPQ4019 includes a modified version of the QCA8K Ethernet
switch. The switch's CPU port is connected to the SoC through the internal
EDMA Ethernet controller. Add support for these two devices, which are
coupled tightly enough to justify treating them as a single device.
