ASoC: simple-card: support snd_soc_dai_link_component style for cpu
Browse files Browse the repository at this point in the history 
ASoC supports modern style dai_link (= snd_soc_dai_link_component) for
CPU. legacy style dai_link (= cpu_dai_name, cpu_name, cpu_of_node) are
no longer needed.
This patch switches to modern style.
