When a DMA client requests and configures a DMA channel, it requests data_width in Bytes. The DMA40 driver then swiftly converts it over to the necessary register bit value. Unfortunately, for any subsequent calculations we have to shift '1' by the bit pattern (1 << data_width) times to make any sense of it. This patch flips the semantics on its head and only converts the value to its respective register bit pattern when writing to registers. This way we can use the true data_width (in Bytes) value.
