media: mt9m114: Allow set_selection while streaming
The current implementation does not apply changes to the crop-
configuration of the sensor immediately if the sensor is in
streaming state. The user has to stop and restart the stream for
the changes to be applied.
This can be undesirable e.g. in a calibration usecase where the user
wants to see the impact of his changes in a live video stream.
Under the condition that the width & height of the cropped image area
does not change, the changed cropping configuration can be applied to
the pixel-array immediately without disturbing the IFP.
Call mt9m114_configure_pa() in mt9m114_pa_set_selection() if the sensor is
in streaming state and the size of the cropping rectangle didn't change,
issue a CONFIG_CHANGE to apply the changes immediately.
