Removing subdevice nodes is easier. But I was referring to your v1 feedback

"entities formats should be independent, it is up to link_validate
to check formats between entities.
The capture shouldn't change the format of the subdevice"

If we all agree to have video node do all pipeline formats, which is 
what I have in v1, will revert to that in v3.
