[PATCH] ASoC: fsl_esai: Add pm runtime function

In imx8 when systerm enter suspend state, the power of subsystem will be off, the clock enable state will be lost and register configuration will be lost. So the driver need to enter runtime suspend state in suspend. With this implementation the suspend function almost same as runtime suspend func
