Subject: [PATCH] drm/virtio: add definition for venus capset

This definition is used fro qemu, and qemu imports this marco in the
headers to enable venus for virtio gpu. So it should add it even kernel
doesn't use this.

qemu. Please see details on below discussion:

I've opened request to update virtio-spec with the corrected/updated
capsets https://github.com/oasis-tcs/virtio-spec/issues/182. I'm
expecting that it will take some time until spec change will be merged
and now leaning to apply this v1 patch to not hold the Venus work.

Gerd, do you have objections? R-b/ack?

Applied patch to misc-next with edited commit message. Updating spec
taking much time, not worth to hold this change longer. We'll add the
rest of capsets later on. Thanks, Rui!
