drm/i915/adlp+/dp_mst: Align slave transcoder enabling with spec wrt. DDI function

Browse source

On ADLP+ during modeset enabling configure the DDI function without
enabling it for MST slave transcoders before programming the data and
link M/N values. The DDI function gets enabled separately later in the
transcoder enabling sequence.

Align the code with the spec based on the above.

v2: Move this patch earlier in the series, addressing the DP2
    config fixes for all ADLP+ platforms later.
