Russell King e83b366487 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: 7d35496dd9 ("ARM: 7796/1: scsi: Use dma_max_pfn(dev) helper for bounce_limit calculations")
