[PATCH v2 22/22] drm/i915/display: Use atomic helper to set plane fence deadlines

[Matthew Brost <matthew.brost@intel.com>]

i915 has its own atomic commit path and does not always funnel through
drm_atomic_helper_wait_for_fences(). Reuse the atomic helper deadline
logic by calling drm_atomic_helper_set_fence_deadline() at the start of
intel_atomic_commit().

This sets an advisory deadline on incoming plane fences based on the
next vblank for single-CRTC commits, matching the behavior of the atomic
helper wait path.
