drm/doc: document fallback behaviour for atomic events
Worst case if the hw can't support completion signalling in a
race-free way we want the event to be too late, not too early.
Text adapted from a proposal from Laurent - the other side of how to
make hw work correctly where it's possible is imo already sufficiently
documented.
