video: driver: Add Complexity vs. Operating Rate handling

For Quality mode decision, Complexity and Operating rate
are handled as below -
[1] If Complexity and operating rate both are set,
    then for NRT, complexity is honored, and operating
    rate can be adjusted. But for RT, Operating Rate is
    honored and complexity can be adjusted.
[2] If only Complexity is set, then complexity is honored.
[3] If only Operating rate set then Operating rate is honored
[4] If None set, then upto encoder to decide
