This series implements a driver part of the virtio sound device specification v8 [1].
The driver supports PCM playback and capture substreams, jack and channel map controls. A message-based transport is used to write/read PCM frames to/from a device.
As a device part was used OpenSynergy proprietary implementation.
v5 changes:
- Fixed another bunch of sparse warnings (replaced virtio_cread() -> virtio_cread_le()), no functional changes.
(Sorry, I didn't know how to run sparse locally, now everything should be fixed)

In the future please number patches from 1, not from 2. thanks!
But they are numbered automatically by git. Patch #1 is for virtio_ids.h
Weird somehow I was missing patch #1. Applied now, thanks!
