  rpmsg: glink: Release driver_override (2023-02-15 07:46:02 -0800)

----------------------------------------------------------------
rpmsg updates for v6.3

rpmsg ctrl and char driver locking is ensure ordering in cases where the
communication link is being torn down in parallel with calls to open(2)
or poll(2).

The glink driver is refactored, to move rpm/smem-specifics out of the
common logic and better suite further improvements, such as transports
without a mailbox controller. The handling of remoteproc shutdown is
improved, to fail clients immediately instead of having them to wait for
timeouts. A driver_override memory leak is corrected and a few spelling
improvements are introduced.

glink_ssr is transitioned off strlcpy() and "gpr" is added as a valid
child node of the glink-edge DT binding.
