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.
