ALSA: hda - chmap helper args modified to use generic hdac objs.
Chmap helper arguments are modified to use either hdac_device object or hdac_chmap object instead of codec specific object. With this moving these APIs to core will be easier. Helper added to access a specific channel_allocation object instead of directly accessing. Signed-off-by: Subhransu S.
