drm/i915: WARN on lack of shared dpll
Now that we have proper hw state reconstruction we should never have a case where we don't have the software dpll state properly set up. So add WARNs to the respective !pll cases in enable/disabel_shared_dpll. Reviewed-by: Damien Lespiau <damien.lespiau@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
