DMA bounce limit is the maximum direct DMA'able memory beyond which bounce buffers has to be used to perform dma operations. MMC queue layr relies on dma_mask but its calculation is based on max_*pfn which don't have uniform meaning across architectures. So make use of dma_max_pfn() which is expected to return the DMAable maximum pfn value across architectures.
