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