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
