Some boards support NVME drives. We should be able to use them as boot devices.
NVME access requires running 'nvme scan'.

BUT
with CONFIG_BLK we can enumerate all block devices without all of this mess and we should be able to probe them too.
All nvme_scan_namespace() does is probe all the devices. We could do the same thing generically.
So, I suggest we simplify this distro stuff to scan CONFIG_BLK and we can drop most of the code and complexity.
I think that's a great idea. We would need some new command for that though. Something like "blk"?
Given that this is bigger rework, I'll apply this patch as interim stop-gap regardless - booting from NVMe is useful today.
Going forward we should then move to a new, more generic block storage access command.
