[Intel-gfx] [PATCH 1/2] drm/i915: handle sdvo input pixel multiplier correctly again

[Daniel Vetter]

The sdvo input timing needs to be the actual mode, the sdvo
encoder automatically adjusts for the need of pixel doubling or
quadrupling. This was lost in pipe config conversion of the
pixel multiplier in

    drm/i915: add pipe_config->pixel_multiplier

While at it ditch the intel_ prefix from the crtc in
intel_sdvo_mode_set.
