This commit exposes following functions which can be used by a sound card driver based on audio graph driver. Idea is vendors can have a thin driver and re-use common stuff from audio graph driver.
- graph_card_probe() - graph_get_dais_count() - graph_parse_of()
In doing so a new header file is added for audio graph which can be included by vendor drivers.
