I've submitted more patches to save size, changes here were
not enough to fix building tbs2910 board with DM video enabled.

All boards using ipuv3 driver are now converted, I'll submit a
pull request to merge the changes.

For boards with only DM video conversion missing, it makes sense
to disable video, but I don't know is this can be done for all
such boards (some do not have serial console and rely on working
display output). Some boards do not even enable DM, these are
candidates to drop.

Patch already submitted to drop non-DM code here.
