dmaengine: fsl-edma: select of_dma_xlate based on the dmamuxs presence

Select the of_dma_xlate function based on the dmamuxs definition rather
than the FSL_EDMA_DRV_SPLIT_REG flag, which pertains to the eDMA3
layout.

This change is a prerequisite for the S32G platforms, which integrate both
eDMAv3 and DMAMUX.

Existing platforms with FSL_EDMA_DRV_SPLIT_REG will not be impacted, as
they all have dmamuxs set to zero.
