commit 896e5bb022bce64e29ce2e1b2fc2a7476d311a15 upstream.

Since we have to write ddb allocations at the same time as we do other plane updates, we're going to need to be able to control the order in which we execute modesets on each pipe. The easiest way to do this is to just factor this section of intel_atomic_commit_tail() (intel_atomic_commit() for stable branches) into it's own function, and add an appropriate display function hook for it.

Based off of Matt Rope's suggestions

Changes since v1:
- Drop pipe_config->base.active check in intel_update_crtcs() since we check that before calling the function

[omitting CC for stable, since this patch will need to be changed for such backports first]
