This patchset introduces multiple streaming in VIMC piepline handler.
The first patch in this series moves a helper to determine raw formats
to PixelFormatInfo class, while rest introduce multiple streams (1 RAW
and 1 RGB/YUV) to the pipeline handler.
VIMC does not support multiple streams yet, so I used a patchset by
Niklas to introduce the same. The link to patchset is: 
https://patchwork.kernel.org/cover/10948831/
Since this patchset is old, I will follow this patchset (Introduce
multiple streams to the pipeline handler) with Niklas' patch rebased on
the current media-tree so that it becomes easy to test my patchset.

I tested this patchset with cam. The non-exhaustive list of commands
I tried are:
cam -c 1 -C -s role=viewfinder -s role=stillraw
cam -c 1 -C -s height=30,width=30 -s height=50,width=50
cam -c 1 -C -s role=stillraw
cam -c 1 -C -s height=50,width=50 -s height=20,width=20
