DMA-API: net: octeon: use dma_coerce_mask_and_coherent()
The code sequence:
pdev->dev.coherent_dma_mask = DMA_BIT_MASK(64);
pdev->dev.dma_mask = &pdev->dev.coherent_dma_mask;
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.
