ASoC: core: add support to snd_soc_dai_get_channel_map()
On Qualcomm platforms, specifically with SLIMbus interfaced codecs, the codec slim channel numbers are passed to DSP while configuring the slim audio path. Having get_channel_map() would allow dais to share such information across multiple dais.
