[2/6] rpmsg: glink: smem: Wrap driver context
Commit Message
The Glink SMEM driver allocates a struct device and hangs two
devres-allocated pipe objects thereon. To facilitate the move of
interrupt and mailbox handling to the driver, introduce a wrapper object
capturing the device, glink reference and remote processor id.
The type of the remoteproc reference is updated, as these are
specifically targetting the SMEM implementation.

Would it be proper to keep a pointer to dev and avoid all the changes to
smem->dev use?
