DMA: dmatest: extend the "device" module parameter to 32 characters

With Device Tree a typical DMA controller device name can look like 10000000.dma-controller, which extends the current size of the string, allocated for this parameter. This patch extends its size from 20 to 32 characters. Signed-off-by: Guennadi Liakhovetski <[email protected]> Signed-off-by: Vinod Koul <[email protected]>
