Log Message:
Rework octeon_rnm(4) random number generator driver.
- Do a little on-line self-test for fun.
- Draw raw samples from the ring oscillators.
- Draw substantially more samples:
=> early RO samples seem to have considerably lower entropy
=> consecutive RO samples are not independent
- Make sure to use rnd_add_data_sync in the callback.
=> not technically needed in HEAD, but would be needed for pullup
