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. 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 v4:
- Resending by removing approved patches
Changes since v3:
- Change to device_add_group for rpmsg name attr
- Add patch to unregister the rpmsg device
- Add patch to support compat ioctl for rpmsg char driver
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
