Node names should be somehow generic.

So here, we need to have something like:

mqs1: mqs@<ip_addr>

similar for mqs2.

There is no ip address for mqs module.  The only control register is
in BLK_CTRL.

there are include/dt-bindings/dma/fsl-edma.h
5 suppose should be

FSL_EDMA_MULTI_FIFO | FSL_EDMA_RX
