dmaengine: fsl-edma: integrate v3 support

Browse source

Significant alterations have been made to the EDMA v3's register layout.
Now, each channel possesses a separate address space, encapsulating all
channel-related controls and statuses, including IRQs. There are changes
in bit position definitions as well. However, the fundamental control flow
remains analogous to the previous versions.

EDMA v3 was utilized in imx8qm, imx93, and will be in forthcoming chips.
