[Intel-gfx] [PATCH 0/5] drm/i915/icl: Fix HDMI infoframe setting

On ICL setting the HDMI infoframe requires the pipe clock to be enabled,
this patchset makes sure this is the case both during enabling and
disabling the output.

After discussing with Ville, the only constraint seems to be wrt. other
platforms is that the infoframe is set when the transcoder function is
disabled, see patch 3 for details.
