dmaengine: mcf-edma: utilize edma_write_tcdreg() macro for TCD Access 



The TCD structure has undergone modifications, incorporating fields
extended to 64 bits. When TCD64 is enabled, the TCD type shifts to
'void *'. Use of the edma_write_tcdreg() macro to facilitate TCD register
access.

Add cpu_to_le32(0) to ensure little-endian compatibility with TCD
registers and avoid a build warning.
