MLK-10903-1: ASoC: fsl_spdif: remove cache only in suspend/resume

In imx6qp, there is no mega fast. After suspend, but before resume,
there will be spdif interrupt, if set cache only in suspend, then we
can't clear the interrupt, because regmap_write only write to cache.
So the system will hang for the interrupt can't be cleared.
