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.
