As said in patch [1/2] the IPA will need to use the BDS configuration
because it configures a grid to get AWB statistics from the firmware.
Those statistics are then used to apply a bunch of parameters.

This is one fast and easy way to do it, but probably not the best call.
The main issue is probably removing the 'const' from data_ in
IPU3CameraConfiguration.

As I need the BDS to continue my AWB/AGC implementation, and don't want
to be blocked for too long, I am using this for the moment :-).
