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.
