This subdev interface exposes the internal scaler and color converter
functionality to user space. Resolution and media bus format can now
be configured explicitly by applications. Camera frame composition
onto the output buffer can be confgured through set/get_crop at FIMC.{n}
source pad. Additionally crop, controls and composition may be
reconfigured while streaming.
