[libcamera-devel] [PATCH v3 6/7] build: controls: Add Raspberry Pi vendor specific controls

[Naushir Patuck]

Add a new control_ids_rpi.yaml file to hold the Raspberry Pi specific
vendor controls. This contains a single control PispConfigDumpFile that
will be used in the Pi 5 pipeline handler as a trigger to dump the
Backend configuration as a JSON file.
