ipu3: Disallow raw only camera configuration
To capture raw frames, the ImgU isn't needed. However, to implement
auto-exposure, we do need to configure the IPA since it shall setup
the sensor controls (exposure, vblank and so on) for the capture.
One cannot simply configure the IPA, without the ImgU as the
parameters and statistics buffer passed to the IPA are actually
managed by the ImgU.
Until we prepare and setup the ImgU to run an internal queue for
raw-only camera configuration, disallow this configuration and
report it as invalid.
