[PATCH] drm/i915/skl: Set dirty_pipes to active_crtcs, not ~0

[Lyude]

Using intel_state->active_crtcs allows us to more easily check whether
or not we've updated all of the CRTCs that needed ddb updates since we
can just do:

        mask_of_crtcs_we_updated == intel_state->wm_results.dirty_pipes
