Similar to HDMI, DP uses audio infoframes as well which are structured
very similar to the HDMI ones.
This patch adds a helper function to pack the HDMI audio infoframe for
DP, called hdmi_audio_infoframe_pack_for_dp().
hdmi_audio_infoframe_pack_only() is split into two parts. One of them
packs the payload only and can be used for HDMI and DP.

I agree with this change, as hdmi_audio_infoframe_check_only()'s param is a const,
but you really should mention that you're constifying this one in your commit
description, or do that in a separate commit.
Either of the two is fine.
