Subject: [PATCH v2 3/5] dmaengine: mcf-edma: force type conversion for TCD pointer

The TCD structure undergoes changes, with some fields extending to 64 bits.
When TCD64 is enabled, the type of TCD changes to 'void *' . This addresses
the need to force the type conversion to 'struct fsl_edma_hw_tcd *' at
here.
