Rename to SECURE to align with the CS flag naming.

I was rather close to given an acked-by, but then thought if that
actually makes sense.
The flags describe what should happen to the buffer and CS, and
considering that to distinct that actually makes sense.
In other words the buffer is encrypted and because of this can only be
accessed by a secure submission.

Christian.

Several other teams thought it would be cleaner to call it SECURE
since it aligns better with the CS interface. I don't have a
strong opinion either way.
