rpmsg updates for v4.9

Browse source 
The bulk of these patches involve splitting the rpmsg implementation into a
 framework/API part and a virtio specific backend part. It then adds the
 Qualcomm Shared Memory Device (SMD) as an additional supported wire format.
 
 Also included is a set of code style cleanups that have been lingering for a
 while.
