remove the lightnvm subsystem
Lightnvm supports the OCSSD 1.x and 2.0 specs which were early attempts
to produce Open Channel SSDs and never made it into the NVMe spec
proper. They have since been superceeded by NVMe enhancements such
as ZNS support. Remove the support per the deprecation schedule.
