Relocates the tcd into the fsl_dma_chan structure. This adjustment reduces
the need to reference back to fsl_edma_engine, paving the way for EDMA V3
support.
Unified the edma_writel and edma_writew functions for accessing TCD
(Transfer Control Descriptor) registers. A new macro is added that can
automatically detect whether a 32-bit or 16-bit access should be used
based on the structure field definition. This provide better support
64-bit TCD with future v5 version.

Move the common part of IRQ handler from fsl-edma-main.c and
mcf-edma-main.c to fsl-edma-common.c. This eliminates redundant code, as
the both files contains mostly identical code.

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.

Exported functions in fsl-edma-common.c are only used within
fsl-edma.c and mcf-edma.c. Global export is unnecessary.
This commit removes all EXPORT_SYMBOL_GPL in fsl-edma-common.c,
and renames fsl-edma.c and mcf-edma.c to maintain the same
final module names as before, thereby simplifying the codebase.
