In order for the CameraSensorHelper to be instantiated, we need to find
its factory using the camera sensor model name stored in
IPASettings::sensorModel. As we don't need to do it at each configure
call (the sensor is not changing in-between), implement the init call in
IPAIPU3 to do that.

Mmmmh, I missed a squash, this patch is not the correct one... :-(
