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.
