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.

-pblk: Physical Block Device Target
-==================================
-
-pblk implements a fully associative, host-based FTL that exposes a traditional
-block I/O interface. Its primary responsibilities are:
-
- - Map logical addresses onto physical addresses (4KB granularity) in a
- logical-to-physical (L2P) table.
- - Maintain the integrity and consistency of the L2P table as well as its
- recovery from normal tear down and power outage.
- - Deal with controller- and media-specific constrains.
- - Handle I/O errors.
- - Implement garbage collection.
- - Maintain consistency across the I/O stack during synchronization points.
-

-contacts, etc.
