ipa: rpi: Handle controls for mono variant sensors

Do not advertise colour related controls (i.e. [A]WB, colour saturation)
in the ControlInfoMap of available controls returned out to the
application.

Silently ignore these controls in the control handler in case applications
don't use the advertised ControlInfoMap to validate controls.

As a drive-by fix, don't advertise controls::ColourCorrectionMatrix in
the ControlInfoMap as it is not handled by the IPA.
