drm/atomic: Add struct drm_crtc_commit to track async updates
Split out from my big nonblocking atomic commit helper code as prep
work. While add it, also add some neat asciiart to document how it's
supposed to be used.
v2: Resurrect misplaced hunk in the kerneldoc.
v3: Wording improvements from Liviu.
