DMA-API: mmc: sdhci-acpi: use dma_coerce_mask_and_coherent()

Browse Source 
The code sequence:
	dev->dma_mask = &dev->coherent_dma_mask;
	dev->coherent_dma_mask = 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.
