Hien Huynh 6ea18981bb dmaengine: sh: rz-dmac: Fix destination and source data size setting
commit c6ec8c83a2 upstream.

Before setting DDS and SDS values, we need to clear its value first
otherwise, we get incorrect results when we change/update the DMA bus
width several times due to the 'OR' expression.

Fixes: 5000d37042 ("dmaengine: sh: Add DMAC driver for RZ/G2L SoC")
