Common chmap object represents multichannel capablity and contains chmap ops. Legacy driver is udpated to use this and later ASoC hdac hdmi driver will also use.

In the mixer control callback handlers, information specific to driver are accessed through ops. Also during chmap control registration, use the common hdmi_chmap object instead of hda_codec.
