drm/i915/display: Use external dependency loop for port sync

This loop was added directly to intel_atomic_check() to be used by
all other features that have external pipe dependencies, so using it
and removing intel_atomic_check_synced_crtcs().

After this changes is_trans_port_sync_master() it not used anywhere,
so removing it.
