dmaengine: fsl-edma: move tcd into struct fsl_dma_chan
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.
