Please consider this patch abandoned.  Since I had other reasons to
send out a v5 of the original series this is now squashed in.  See:

https://lore.kernel.org/r/20200507143354.v5.4.Ifcdc4ecb12742a27862744ee1e8753cb95a38a7f@changeid

NOTE that patch #1 in this series, AKA ("drm/bridge: ti-sn65dsi86:
Implement lane reordering + polarity") is still sane/valid and still
applies just fine atop my v5 series.
