media: media.h: Add new media link type
To describe in the kernel the connection between devices and their supporting peripherals (for example, a camera sensor and the vcm driving the focusing lens for it), add a new type of media link to introduce the concept of these ancillary links. Add some elements to the uAPI documentation to explain the new link type, their purpose and some aspects of their current implementation.
