Russell King (Oracle) d622f8477a nvme-apple: don't limit DMA segement size
NVMe uses PRPs for data transfers and has no specific limit for a single
DMA segement.  Limiting the size will cause problems because the block
layer assumes PRP-ish devices using a virt boundary mask don't have a
segment limit.  And while this is true, we also really need to tell the
DMA mapping layer about it, otherwise dma-debug will trip over it.
