The HDMI channel map helper APIs and control registration can be reused by ASoC skylake HDMI drivers.
A common chmap object is created, channel map control callback handlers, helper APIs and data structures are moved to the core. Driver object store an instance of this chmap object to register chmap controls and program channel allocation for HDMI infoframe. Driver registers ops for specific operations.
