remoteproc: remove the now-redundant kref
Now that every rproc instance contains a device, we don't need a kref anymore to maintain the refcount of the rproc instances: that's what device are good with! This patch removes the now-redundant kref, and switches to {get, put}_device instead of kref_{get, put}. We also don't need the kref's release function anymore, and instead, we just utilize the class's release handler (which is now responsible for all memory de-allocations).
