MLK-20060-5 dts: lpspi: add dma mode support
Add dma configurations in dts files, for imx7ulp and imx8qm.
There is no "edma0" node in fsl-imx8qm-mek(or lpddr4-arm2)-domu.dts.
lpspi0 node has been deleted in these dts files, so delete lpspi3 node.
Add edma0a and edma0d for lpspi0 and lpspi3, and enable lpspi0/3 for xen.
