SimpleCameraConfiguration::validate() looks for the best configuration. As part of enabling raw stream support, the method must consider raw streams in addition to the processed streams. Raw streams are adjusted from the capture format and size. Note that with both processed and raw streams, the requested sizes must be mutually matching, including resizing due to debayer requirements. For example, the following `cam' setup is valid for imx219 cam -s role=viewfinder,width=1920,height=1080 \ -s role=raw,width=3280,height=2464 rather than cam -s role=viewfinder,width=1920,height=1080 \ -s role=raw,width=1920,height=1080 due to the resolution of 1924x1080 actually selected for debayering to 1920x1080. If the resolutions don't match mutually or don't match the available sizes, validation adjusts them. Setting up the right configurations is still not enough to make the raw streams working. Buffer handling must be changed in the simple pipeline, which is addressed in followup patches.
