drm/atomic-helper: Add an atomice best_encoder callback
With legacy helpers all the routing was already set up when calling best_encoder and so could be inspected. But with atomic it's staged, hence we need a new atomic compliant callback for drivers which need to inspect the requested state and can't just decided the best encoder statically. This is needed to fix up i915 dp mst where we need to pick the right encoder depending upon the requested CRTC for the connector. v2: Don't forget to amend the kerneldoc Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Theodore Ts'o <tytso@mit.edu> Acked-by: Thierry Reding <treding@nvidia.com> Reviewed-by: Ander Conselvan de Oliveira <conselvan2@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
