[PATCH 1/1] staging: ipu3-imgu: Move the UAPI header from include under include/uapi

[Sakari Ailus]

The header defines the user space interface but may be mistaken as
kernel-only header due to its location. Add "uapi" directory under
driver's include directory and move the header there.

-"VIDEO" or "STILL", "VIDEO" mode is commonly used for video frames capture, and
-"STILL" is used for still frame capture. However, you can also select "VIDEO" to
-capture still frames if you want to capture images with less system load and

-larger bayer frame for further YUV processing than "VIDEO" mode to get high
