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.
