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.
