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.
Fixes: 5bd2927aceba ("nvme-apple: Add initial Apple SoC NVMe driver")
