The pixelformat describes the image format in memory, the mbus_framefmt describes the image data as it is transferred over a hardware bus. It's as simple as that. While the two are related (i.e. to get a certain pixelformat you probably need to set up a specific mbus_framefmt), the details of this relationship are board or even use-case dependent.
