This patch introduces core structures required for implementing FTL on
top of Open Channel drives. The Open Channel specification describes raw
access to the media on the SSD. The FTL consumes that API and exposes a
block device interface.
The implementation is based on the revision 2.0 of the Open Channel SSD
specification.
