dt-bindings: dma: fsl,edma: Add i.MX94 support

Add support for the i.MX94 DMA controllers. The SoC includes two DMA
controllers: one compatible with i.MX93 eDMA3 and another compatible with
i.MX95 eDMA5.

Add compatible string "fsl,imx94-edma3" with fallback to "fsl,imx93-edma3".
Add compatible string "fsl,imx94-edma5" with fallback to "fsl,imx95-edma5".
