This is the next round of my patches for the nvme device.

This includes a bit of cleanup and three new features:

  * refactored aio submission
    This also adds support for multiple parallel AIOs per request which is in
    preparation for DULBE, ZNS and metadata support. If it is found
    controversial, it can easily be dropped from this series.

  * support for scatter/gather lists

  * multiple namespaces support through a new nvme-ns device

Finally, the series ends with changing the PCI vendor and device ID to get rid
of the internal Intel id and as a side-effect get rid of some Linux kernel
quirks that no longer applies.

"pci: pass along the return value of dma_memory_rw" has already been posted by
Philippe in another series, but since it is not applied yet, I am including it
here.
