Add support for the GLINK rpmsg transport to register a rpmsg chrdev. This will create the rpmsg_ctrl nodes for userspace clients to open rpmsg epts. Create a label property that will help userspace clients distinguish between the different GLINK links. The rpmsg chrdev allocation is done by allocating a local channel which also allocates an ept. We need to add some guards against edge cases for this chrdev because it will never fully open.
Changes since v2: - Revert change to make glink attribute table const
Changes since v1: - Add explanation to dt-bindings commit message - Add patch complete_all the open_req/ack variables - Add patch to prevent null pointer dereference in chrdev channel release - Change chrdev allocation to use glink channel allocation - Change glink attr struct to const
