[PATCH v2 04/12] dmaengine: fsl-edma: remove v3 from enum edma_version

[Frank Li]

The new IP of edma refers to version 3 in the hardware documentation.
However, the presence of "v3" in the code is merely a software indication
to differentiate between certain chips. To prevent confusion in the
future, this commit removes "v3" from the enum edma_version.
