nvme: add 48-bit DMA address quirk for Amazon NVMe controllers
Some Amazon NVMe controllers do not follow the NVMe specification and are limited to 48-bit DMA addresses. Add a quirk to force bounce buffering if needed and limit the IOVA allocation for these devices. This affects all current Amazon NVMe controllers that expose EBS volumes (0x0061, 0x0065, 0x8061) and local instance storage (0xcd00, 0xcd01, 0xcd02).
