Subject: [PATCH net-next v2 2/8] dt-bindings: remoteproc: k3-r5f: Add rpmsg-eth subnode

Extend the Texas Instruments K3 R5F remoteproc device tree bindings to
include a 'rpmsg-eth' subnode.

This extension allows the RPMsg Ethernet to be defined as a subnode of
K3 R5F remoteproc nodes, enabling the configuration of shared memory-based
Ethernet communication between the host and remote processors.
