drm/i915/ptl/dp_mst: Fix slave transcoder enabling wrt. DDI function
On PTL 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.
This fixes a slave transcoder getting stuck during enabling, leading
to page flip timeout errors on the corresponding pipe.
The spec requires the same programming step for ADLP+ platforms, that
will be addressed separately (on those platforms the above transcoder
getting stuck issue was not observed).
