[PATCH v2 11/14] libcamera: camera_sensor: Drop updateControlInfo() function

[Laurent Pinchart]

The CameraSensor::updateControlInfo() function is a wrapper around the
same function of the V4L2Subdevice class. It was meant to be called by
pipeline handlers that modify the sensor configuration directly,
bypassing the CameraSensor::setFormat() function. This never happened,
and the function is called once only, internally to the CameraSensor
class. No external users are foreseen, drop the function and call
V4L2Subdevice::updateControlInfo() directly.
