MLK-15937-4: ASoC: fsl_spdif: Use DMA workaround for SPDIF
Similar with commit 2f756e7aa88407 ("MLK-15004-4: ASoC: fsl_esai: esai
workaround for imx8qxp Rev1") this is needed because of a hardware
issue where SPDIF DMA request signal is active low but the DMA
input is active high.
The workaround uses GPT to convert DMA request signal to EDMA.
