dmaengine: fsl-edma: Remove enum edma_version
The enum edma_version, which defines v1, v2, and v3, is a software concept
used to distinguish IP differences. However, it is not aligned with the
chip reference manual. According to the 7ulp reference manual, it should
be edma2. In the future, there will be edma3, edma4, and edma5, which
could cause confusion. To avoid this confusion, remove the edma_version
and instead use drvdata->flags to distinguish the IP difference.
