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.
