pipeline: rpi: Move flip handling validation code
Move the handling of Bayer order changes due to flips to run before platformValidate(). This removes the need for this code to be split between platformValidate() and validate() as it is right now. Also add some validation to ensure the vc4 pipeline handler only supports CSI2 packing or no packing.
