lightnvm: update bad block table format
The specification was changed to reflect a multi-value bad block table.
Instead of bit-based bad block table, the bad block table now allows
eight bad block categories. Currently four are defined:
* Factory bad blocks
* Grown bad blocks
* Device-side reserved blocks
* Host-side reserved blocks
The factory and grown bad blocks are the regular bad blocks. The
reserved blocks are either for internal use or external use. In
particular, the device-side reserved blocks allows the host to
bootstrap from a limited number of flash blocks. Reducing the flash
blocks to scan upon super block initialization.
Support for both get bad block table and set bad block table is added.
