libcamera: camera_sensor: Restrict sensor info to raw sensors
YUV sensors don't provide the necessary information to fill
CameraSensorInfo, as they include an ISP and provide a higher-level API
that doesn't always expose low-level information. The CameraSensor class
makes low-level V4L2 controls mandatory for all sensors, which prevents
usage of YUV sensors with the simple pipeline handler.
Make CameraSensor::sensorInfo() available for raw sensors only. This
won't introduce any regression in pipeline handlers that currently use
the sensorInfo() function as they all operate with raw sensors, and
won't be a limitation for the simple pipeline handler as well as it
doesn't use sensor info. If part of the sensor info (such as the active
pixel array size for instance) becomes useful to expose for YUV sensors
in the future, the sensorInfo() function can be extended to report that
information only and skip data that is only available for raw sensors.
