Revert "ARM: dts: imx: use dual-fifo sdma script for ssi"
This reverts commit b1d27c79c8377df1880447375deffa3bb82c7bd3. Previously we switched the SSI scriprt to dual-fifo mode to reduce playback underrun issue, which is only included by SDMA firmware version 2. However, there are quite a lot people still using version 1 or default firmware in the ROM code of SoC while these two kinds of firmwares do not support the dual-fifo script and the audio function on their platform would be broken. Thus this patch provisionally reverts the dual-fifo script to the original single fifo script to meet all kinds of users' requirements, including the version 1/2 or inner ROM firmware.
