Amazon NVMe controllers do not support 64-bit DMA addresses; they are limited to 48-bit DMA addresses. Let's add a quirk to ensure that we make use of 48-bit DMA addresses to avoid misbehavior.This should probably say some, and mention that they do not follow the spec. But I can fix this up when applying the patch.
