v2: bummer, v1 didn't apply cleanly to master (it applied to Kevin's
block tree); rebased to make patchew happy
This adds a new 'nvme-ns' device that attaches to the nvme device
through a bus. This decouples the nvme controller and nvme namespaces
such that multiple namespaces may be attached to the controller.
With this in place, we can allocate a fresh pci vendor/device id and get
rid of the Intel id pair that causes the Linux kernel to apply a bunch
of quirks that the device no longer has.
Based-on: <20200629203155.1236860-1-its@irrelevant.dk>
