drm/atomic_helper: Make it clear that commit_planes gets the old state

Browse Source 
Oversight from my kerneldoc cleanup when doing the original atomic
helper series - I've only applied this clarification to the modeset
related helpers, and not the plane update code. Remedy this asap.

* drm_atomic_helper_commit_planes - commit plane state
* @dev: DRM device
* @state: atomic state
* @old_state: atomic state object with old state structures
*
* This function commits the new plane state using the plane and atomic helper
* functions for planes and crtcs. It assumes that the atomic state has already
* been pushed into the relevant object state pointers, since this step can no
* longer fail.
*
* It still requires the global state object @state to know which planes and
* It still requires the global state object @old_state to know which planes and
* crtcs need to be updated though.
