ftl: Added initialization module 



This patch adds OCSSD device initialization consisting of the
following:
 * retrieving SSD's geometry and its state
 * verifying configuration
 * initializing core structures (L2P, bands, write buffer, write
 pointers, bad block tables, etc)
 * initializing threads
