From: Marc-André Lureau <marcandre.lureau@xxxxxxxxxx>
Some scanouts during boot are top-down without it.
y0_top is set from VHOST_USER_GPU_DMABUF_SCANOUT code path in the last
patch of this series.
In current QEMU code base, only vfio/display uses dmabuf API. But the
VFIO query interface doesn't provide or need that detail so far.
