Use this in all the places where we try to acquire planes after the planes
atomic_check().
In case of intel_modeset_all_pipes() this is not yet done after atomic_check,
but seems like it will be in the future. To add some paranoia, add all planes
rather than active planes, because of bigjoiner and planar YUV support having
extra planes outside of the core's view that wouldn't be added otherwise.
Changes since v1:
- Always add all planes, to handle force plane updates to work correctly
with a disabled cursor plane.
