The i.MX Image Processing Unit (IPU) contains a number of image processing blocks that sit right in the middle between DRM and V4L2. Some of the modules, such as Display Controller, Processor, and Interface (DC, DP, DI) or CMOS Sensor Interface (CSI) and their FIFOs could be assigned to either framework, but others, such as the dma controller (IDMAC) and image converter (IC) can be used by both. The IPUv3 core driver provides an internal API to access the modules, to be used by both DRM and V4L2 IPUv3 drivers.

Changes since RFC:
- Rebased onto current staging-next
- Removed an unrelated change to ipu_pixelformat_to_colorspace
- Avoided moving around the IPU_PIX_FMT_GBR24 #define
