ASoC: fsl_spdif: Fix unexpected interrupt after suspend
When system enter suspend, the machine driver suspend callback function will be called, then the cpu driver trigger callback (SNDRV_PCM_TRIGGER_SUSPEND) be called, it would disable the interrupt. But the machine driver suspend and cpu dai driver suspend order maybe changed, the cpu dai driver's suspend callback is called before machine driver's suppend callback, then the interrupt is not cleared successfully in trigger callback. So need to clear interrupts in cpu dai driver's suspend callback to avoid such issue.
