ef2e614cef ftl: Initial implementation
This patch adds core FTL (flash translation layer) submodules.

On regular SSDs the FTL is part of firmware, whereas Open Channel
enables moving it to the host and allows for having full controll
of data placement on the device.

Main functionalities added:
 * logical to physical address map
 * read / write buffer cache
 * wear-leveling
 * bad block management
