drm/atomic: refactor planes names

We are currently using primary / overlay planes drm objects, assuming that primary plane is osd and overlay plane is video.
This commit is doing two things :
  - replace the primary / overlay planes members with osd and video planes member without the assumption
  - Add two more options to determine which one of the primary / overlay is associated to osd / video.
  - It will default osd to overlay and video to primary if unspecified
