ASoC: add snd_soc_of_get_dai_name() default of_xlate
Current snd_soc_of_get_dai_name() needs .of_xlate_dai_name() callback on each component drivers. But required behavior on almost all these drivers is just returns its indexed driver's name. This patch adds this feature as default behavior. .of_xlate_dai_name() can overwrite it.
