Subject: [PATCH 3/3] arm64: dts: imx8mm: fix micfil dmas settings

The third dma cell is used for priority information not to encode
something else. The NXP downstream kernel use the third cell to encode
more information:

 - Bit31: sw_done feature enable/disable
 - Bit15~Bit8: selector
 - Bit7~Bit0: priority level

but this was never mainlined. Therefore drop the further information and
just specify the priority which is 0.

FTR: The sw_done feature was mainlined without making use of the
devicetree.
