i.MX8QXP contains a total of 4 EDMA controllers of which
two are primarily for audio components and the other two
are for non-audio periperhals.

This patch adds the EDMA0/EDMA1 nodes used by audio peripherals.

EDMA0 contains channels for:
	* ASRC0
	* ESAI0
	* SPDIF0
	* SAI0, SAI1, SAI2, SAI3

EDMA1 contains channels for:
	* ASRC1
	* SAI4, SAI5

See chapter Audio DMA Memory Maps (2.2.3) from i.MX8QXP RM [1]

This patch is based on the dtsi file initially submitted by
Teo Hall in i.MX NXP internal tree.

In binding doc, it's 2.
- #dma-cells : Must be <2>.
        The 1st cell specifies the DMAMUX(0 for DMAMUX0 and 1 for DMAMUX1).
        Specific request source can only be multiplexed by specific channels
        group called DMAMUX.
        The 2nd cell specifies the request source(slot) ID.

Need update binding doc?

Undocumented property?

Checkpatch did not complain?

Thanks Aisheng for this comment. I think we might need to delay a little bit
this patch because (as pointed by Yibin) on i.MX8 QXP/QM we use
fsl-edma-v3 which *is not* yet upstream.

So, lets get back to adding the nodes after Yibin sends edma-v3 patches.

thanks,
Daniel.

Yes, Yibin could check the comments when resending with edma driver support.
