The other way around.  The plan is that CONFIG_NVME_MULTIPATH will
stay around forever - for deeply embedded devices that only have
a soldered on or sd-card nvme device with a single path there is no
need to carry the multipathing code around.  But the code to support
multiple controllers in a subsystem without CONFIG_NVME_MULTIPATH
will go away.
