libcamera: imx8-isi: Split Bayer/YUV config generationisi/raw_sensor
The ISI can:
- produce any processed (YUV/RGB) stream format from a non-Raw media bus
format
- produce Bayer Raw stream formats from a Bayer RAW media bus format
At generateConfiguration() a YUV/RGB pixel format is preferred for the
StillCapture/VideoRecording/Viewfinder roles, but currently there are no
guarantees in place that the sensor provide a non-Bayer bus format from
which YUV/RGB an be generated.
This makes the default configuration generated for those roles not to
work if the sensor is a RAW-only one.
To improve the situation split the configuration generation in two:
- One for YUV modes
- One for Raw Bayer mode
StreamRoles assigned to a YUV mode will try to first generate a YUV
configuration and then fallback to RAW if that's what the sensor can
provide.
As an additional requirement, for YUV streams, the generated mode has to
be validated with the sensor to confirm the desired sizes can be
generated. In order to test a format on the sensor introduce
CameraSensor::tryFormat().
