drm/i915: add pipe_config->has_pch_encoder
This is used way too often in the enable/disable paths. And will be even more useful in the future. Note that correct semantics of this change highly depend upon correct updating of intel_crtc->config: Like with all other modeset state, we need to call ->disable with the old config, but ->mode_set and ->enable with the new config. v2: Do not yet use the flag in the ->disable callbacks - atm we don't yet have support for the information stored in the pipe_config in the hw state readout code, so this will be wrong at boot-up/resume. v3: Rebased on top of the hdmi/dp ddi encoder merging. v4: Fixup stupid rebase error which lead to a NULL vfunc deref. v5: On haswell the VGA port is on the PCH! v6: s/IS_HASWELL/HAS_DDI/, spotted by Paulo Zanoni. Also add a missing parameter name in a function declaration. v7: Don't forget to git add ... Reviewed-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
