[Intel-gfx] [PATCH 13/42] drm/i915: Set mode_changed for audio in intel_modeset_pipe_config()

[Maarten Lankhorst]

From: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira at intel.com>

A follow up patch will make intel_modeset_compute_config() deal with
multiple crtcs, so move crtc specific stuff into the lower level crtc
specific function.
