arm64: dts: imx8qm-ss-dma: correct the dma channels of lpuart 

The commit 616effc027 ("arm64: dts: imx8: Fix lpuart DMA channel
order") swap uart rx and tx channel at common imx8-ss-dma.dtsi. But miss
update imx8qm-ss-dma.dtsi.

The commit 5a8e9b022e ("arm64: dts: imx8qm-ss-dma: Pass lpuart
dma-names") just simple add dma-names as binding doc requirement.

Correct lpuart0 - lpuart3 dma rx and tx channels, and use defines for
the FSL_EDMA_RX flag.
