Integrate the RkISP1 pipeline handler to support sensor configuration
provided by applications through CameraConfiguration::sensorConfig.

The SensorConfiguration must be validated on both RkISP1Path (mainPath
and selfPath), so the parameters of RkISP1Path::validate() have been
updated to include sensorConfig.

The camera configuration will be marked as invalid when the sensor
configuration is supplied, if:
- Invalid sensor configuration (SensorConfiguration::isValid())
- Bit depth not supported by RkISP1 pipeline
- RAW stream configuration size doesn't matches sensor configuration
  output size
- Sensor configuration output size is larger than maximum supported
  sensor configuration on RkISP1 pipeline
- No matching sensor configuration output size supplied by the sensor

Can we unify the two if branches ?

Why an optional ?

What about:

	/*
	 * Make sure that if a sensor configuration has been requested it
	 * is valid.
	 */
	if (sensorConfig) {
		if (!sensorConfig->isValid()) {
			LOG(RkISP1, Error)
				<< "Invalid sensor configuration request";
			return Invalid;
		}

		unsigned int bitDepth = sensorConfig->bitDepth;
		if (bitDepth != 8 && bitDepth != 10 && bitDepth != 12) {
			LOG(RkISP1, Error)
				<< "Invalid sensor configuration bit depth";
			return Invalid;
		}
	}

No need for {}  I think

Should this be

			if (sensorConfig && info.bitsPerPixel != sensorConfig->bitDepth)
				continue;

Otherwise if (sensorConfig) and
(info.bitsPerPixel != sensorConfig->bitDepth)

> +			} else if (info.bitsPerPixel > rawBitsPerPixel) {

We can still enter this branch and wrongly pick a format with a
bitDepth != than the one specified in sensorConfig ?

Then, if we exit the for() loop with "found == false && sensorConfig"
you should return invalid ?

nit: you can declare this a few lines below before using it

Isn't it better to first "boundedTo" to make sure maxResolutions_ is
smaller than sensorSize and then "boundedToAspectRatio" to further
shrink it to the aspect ratio of the sensorSize ?

Except the bitDepth handling at the beginning of this function, most
comments are nits, I presume the next version should be good to go

Thanks
