Hello everyone,

Thanks to Umang's review and Han-lin's help on multiple sub-patches,
here's the fourth version of patches to use two imgus in ipu3
pipeline handler, mostly to better support StillCapture, which was
handled as video snapshot.

The patches are tested on soraka.
Please check again and give me more feedbacks. Thanks

BR,
Harvey
