Laurent Pinchart 6418b4d6e1 [media] v4l: vsp1: bru: Support premultiplied alpha at the BRU inputs 
Adjust the BRU blending formula to avoid the multiplication by alpha
when the corresponding input format is premultiplied. As this requires
access to the RPFs connected to the BRU inputs from the BRU module,
store pointers to the RPFs in the BRU structure when validating the
pipeline.
