DMA-API: ata: pata_octeon_cf: convert to use dma_coerce_mask_and_coherent()

Browse Source 
Convert this code sequence:
	pdev->dev.coherent_dma_mask = DMA_BIT_MASK(64);
	pdev->dev.dma_mask = &pdev->dev.coherent_dma_mask;
to use dma_coerce_mask_and_coherent() to avoid bypassing the architecture
check on the DMA mask.
