Add function to copy from yv12 image to nv12 surface for VAAPI putimage call.
We need this function in VaPutImage call where copying from yv12 image to nv12
surface for encoding. Existing function can't be used because it only work for
copying from yv12 surface to nv12 image in Vaapi.
I think we can keep the patches mostly as they are now, but I would like
to get a bit more positive feedback from Andy and maybe others.
E.g. at least we should be able to encode something without crashing on
Tonga and other hardware generations as well before we push it upstream.

Christian.
