ipa: rpi: awb: Make it possible to set the colour temperature directly
ColourTemperature is now exported as a writable control so that applications can set it directly. The AWB algorithm class now requires a method to be provided to perform this operation. The method should clamp the passed value to the calibrated range known to the algorithm. The default range is set very wide to cover all conceivable future AWB calibrations. It will always be clamped before use.
