Subject: [PATCH net-next v4 5/5] ARM: dts: qcom: ipq4019: Add description for the IPQESS Ethernet controller

The Qualcomm IPQ4019 includes an internal 5 ports switch, which is
connected to the CPU through the internal IPQESS Ethernet controller.

This commit adds support for this internal interface, which is
internally connected to a modified version of the QCA8K Ethernet switch.

This Ethernet controller only support a specific internal interface mode
for connection to the switch.
