dmaengine: fsl-edma: add PM suspend/resume support
This add power management suspend/resume support for the fsl-edma
driver.
eDMA acted as a basic function used by others. What it needs to do is
the two steps below to support power management.
In fsl_edma_suspend_late:
Check whether the DMA chan is idle and if it is not idle, stop PM
operation.
In fsl_edma_resume_early:
Enable the eDMA and wait for being used.
