ipa: raspberrypi: Correct some of the ControlInfo ranges and defaults
Some of the values were listed incorrectly. Specifically: ExposureValue: the range is now centred correctly on zero Brightness: the default value (0.0) is made explicit Contrast: the default value is corrected to be 1.0 Saturation: the default value is corrected to be 1.0 Signed-off-by: David Plowman <david.plowman@raspberrypi.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Reviewed-by: Naushir Patuck <naush@raspberrypi.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
