I'm a bit confused whether this is needed so it would be good to
confirm if hw shipped with it.
DAL as currently is doesn't have any support for this, it doesn't
have any encoder ids for DVO that I can see.
So before porting to DAL graphics objects, I'm
DVO was mainly used for crossfire pre-DCE 8, and possibly on some DCE 8
(Tonga) SKUs as well. On newer ASICs crossfire uses XDMA so there's no
longer a need for DVO.
It's probably safe to drop it for amdgpu. Radeon driver might still want
to keep it if there's support for it.
