Fix uses of dma_max_pfn() when converting to a limiting address
We must use a 64-bit for this, otherwise overflowed bits get lost, and
that can result in a lower than intended value set.
Fixes: 8e0cb8a1f6ac ("ARM: 7797/1: mmc: Use dma_max_pfn(dev) helper for bounce_limit calculations")
Fixes: 7d35496dd982 ("ARM: 7796/1: scsi: Use dma_max_pfn(dev) helper for bounce_limit calculations")
