pipeline: ipa: raspberrypi: Handle any externally allocated FrameBuffer

Browse source 
Handle the case where a FrameBuffer that has been externally allocated
(i.e. not through the v4l2 video device) is passed into a Request.

We must store the buffer pointer in the stream internal buffer list to
identify when used.
