Hello everyone,

This is the second version of patches to use two imgus in ipu3 pipeline
handler, mostly to better support StillCapture, which was handled as
video snapshot.

The TODO to tackle the delay one frame issue in the ipu3 HW/FW design is
done in the 9th patch.

The patches are tested on soraka.
Please take a look and give me your thoughts. Thanks!

BR,
Harvey
