DMA-API: parport: parport_pc.c: use dma_coerce_mask_and_coherent()

The code sequence:
dev->coherent_dma_mask = DMA_BIT_MASK(24);
dev->dma_mask = &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.
