[PATCH 6/6] ipa: rpi: Provide the camera helper with the hardware configuration

[Naushir Patuck]

Add a CamHelper::setHwConfig() helper used by the IPA to set the
hardware configuartion in use by the pipeline. This will be needed by
the IMX500 camera helper in a future commit to determine if the
metadata buffer is strided.
