Changelog
v1:
* SSI can reduce hardware overrun/underrun possibility when using dual
* fifo mode. To support this mode, we need to first update sdma sciprt
* list, and then enable dual fifo BIT in SSI driver, and last update DT
* bindings of i.MX series.
*
* ! This series of patches has a direct dependency between them. When
* ! applying them, we need to apply in one single branch. Otherwise,
* ! it would break currect branches.
