[PATCH devicetree 1/2] arm64: dts: ls1028a: Specify the DMA channels for the DSPI controllers

[Vladimir Oltean <olteanv-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

From: Vladimir Oltean <vladimir.oltean-3arQi8VN3Tc@public.gmane.org>

LS1028A has a functional connection to the eDMA module. Even if the
spi-fsl-dspi.c driver is not using DMA for LS1028A now, define the slots
in the DMAMUX for connecting the eDMA channels to the 3 DSPI
controllers.
