Instead of the single parameters buffer file descriptor, pass the file descriptors of all the parameters buffers to the IPA and let it use them according to the passed buffer id. This means: - The file descriptors of all the buffers must be passed to the IPA. - The IPA must store mappings of the buffer ids to the corresponding buffers. - The current buffer id is passed to/from the IPA. The parameters buffers are still copied for debayering, this will be addressed in the next patch.
