ipa: ipu3, mali-c55, rkisp1, rpi: Fix reporting non-scalar controls

The ControlInfos of non-scalar controls that are reported in controls()
must have non-scalar default values for controls that have a defined
size. This is because applications should be able to directly set the
default value from a ControlInfo to the control.

Currently this is relevant to the following controls:
- ColourGains
- ColourCorrectionMatrix
- FrameDurationLimits
- AfWindows

Fix the scalarness of these controls where relevant.
