[Intel-gfx] [PATCH 04/26] drm/i915: Reassign DPLLs only for crtcs going throug .compute_config()

From: Ville Syrjälä Only reassign the pipe's DPLL if it's going through a full .compute_config() cycle. If OTOH it's just getting modeset eg. in order to change cdclk there doesn't seem much point in picking a new DPLL for it. This should also prevent .get_dplls() from seeing a funky port_clock
