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.
