Add new NAN driver flags to indicate support for:
- Synchronization offload and support for additional NAN sync
parameters.
- Support for user space NAN DE implementation which requires the
driver to send DW notification and be able to transmit and receive
SDF frames over NAN device interface with the correct timing.
