ASoC: audio-graph: Expose new members for asoc_simple_priv
Add new members in struct 'asoc_simple_priv'. Idea is to leverage simple or graph card driver as much as possible and vendor can maintain a thin driver to control the behavior by populating these newly exposed members. Following are the members added in 'asoc_simple_priv': - 'ops' struct: In some cases SoC vendor drivers may want to implement 'snd_soc_ops' callbacks differently. In such cases custom callbacks would be used. - 'force_dpcm' flag: Right now simple or graph card drivers detect DAI links as DPCM links if: * The dpcm_selectable is set AND * Codec is connected to multiple CPU endpoints or aconvert property is used for rate/channels. So there is no way to directly specify usage of DPCM alone. So a flag is exposed to mark all links as DPCM. Vendor driver can set this if required. - 'dpcm_selectable': Currently simple or audio graph drivers provide a way to enable this for specific compatibles. However vendor driver may want to define some additional info. Thus expose this variable where vendor drivers can set this if required. Audio graph driver is updated to consider above flags or callbacks. Subsequent patches in the series illustrate usage for above.
