lightnvm: combine 1.2 and 2.0 command flags
Add nvm_set_flags helper to enable core to appropriately set the command flags for read/write/erase depending on which version a drive supports. The flags arguments can be distilled into the access hint, scrambling, and program/erase suspend. Replace the access hint with a "is_seq" parameter. The rest of the flags are dependent on the command opcode, which is trivial to detect and set.
