[PATCH v3 01/19] drm/i915: Use crtc state in intel_modeset_pipe_config

[Maarten Lankhorst <maarten.lankhorst@linux.intel.com>]

Grabbing crtc state from atomic state is a lot more involved,
and make sure connectors are added before calling this function.

Move check_digital_port_conflicts to intel_modeset_checks,
it's only useful to check it on a modeset.
