Naveen Nagar 44219b6029 hw/nvme: 64-bit pi support
This adds support for one possible new protection information format
introduced in TP4068 (and integrated in NVMe 2.0): the 64-bit CRC guard
and 48-bit reference tag. This version does not support storage tags.

Like the CRC16 support already present, this uses a software
implementation of CRC64 (so it is naturally pretty slow). But its good
enough for verification purposes.

This may go nicely hand-in-hand with the support that Keith submitted
for the Linux kernel[1].
