Commit 4e0871333661 ("ASoC: hdmi-codec: fix channel info for
compressed formats") accidentally changed hcp->chmap_idx from
ca_id, the CEA channel allocation ID, to idx, the index to
the table of channel mappings ordered by preference.

Revert this incorrect change so that channel maps are properly
reported again.
Switch this back to ca_id in case of PCM audio so the correct channel
map is reported again and set it to HDMI_CODEC_CHMAP_IDX_UNKNOWN in
case of non-PCM audio so the PCM channel map control returns "Unknown"
channels (value 0).
