DMA-API: net: nxp/lpc_eth: use dma_coerce_mask_and_coherent()

The code sequence:
	pldat->pdev->dev.coherent_dma_mask = 0xFFFFFFFF;
	pldat->pdev->dev.dma_mask = &pldat->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.
