    drm/i915/sdvo: Remove ->mode_set callback

    SDVO is used by both crtcs using the i9xx_ and the ironlake_
    functions. For both cases there is nothing between the
    encoder->mode_set and the encoder->pre_enable calls that touches the
    hardware.

    The vlv_ functions are different since they enable the pll before the
    ->pre_enable hook. But SDVO isn't supported on vlv platforms, so this
    doesn't matter.

    We've also already clean up all the sdvo state computation logic, all
    relevant parts are already in the ->compute_config hook.  So we can
    just get rid of the ->mode_set hook by converting it to a ->pre_enable
    hook.

    Because the docs say ULX doesn't support it on HSW.
