To support multiple cpu DAIs, add cpu_dai and num_cpu_dai in snd_soc_dai_link and snd_soc_pcm_runtime structures similar to support for codec_dai. This is intended as a preparatory patch to eventually support the unification of the Codec and CPU DAI. Inline with multiple codec DAI approach, add support to allocate, init, bind and probe multiple cpu_dai on init if driver specifies that. Also add support to loop over multiple cpu_dai during suspend and resume. This is intended as a preparatory patch to eventually unify the CPU and Codec DAI into DAI components.
