Hi,

This small series makes a small change to how we handle sensor control limits,
particularly gain and exposure.

With this series, we introduce an explicit SensorLimits structure that stores
the limits.  The AGC algorithm has a new member function that accepts this
structure, replacing the existing setMaxShutter() function.  This allows the
AGC to corretly handle limits of gain values which it currently does not do - 
specifically for the imx708 that has a minimum gain of 1.12x.

Thanks,
Naush
