DMA-API: dma: dw_dmac.c: convert to use dma_coerce_mask_and_coherent()
This code sequence:
if (!pdev->dev.dma_mask) {
pdev->dev.dma_mask = &pdev->dev.coherent_dma_mask;
pdev->dev.coherent_dma_mask = DMA_BIT_MASK(32);
}
bypasses the architectures check on the DMA mask. It can be replaced
with dma_coerce_mask_and_coherent(), avoiding the direct initialization
of this mask.
