drm/amd/display: Rename header file link.h to link_service.h

[WHY]
Header file name "link.h" collides with system header when dc is
compiled as a user-mode library

[WHAT]
Rename link.h to link_service.h to avoid name collision

-/* FILE POLICY AND INTENDED USAGE:
- *
- * This header defines link component function interfaces aka link_service.
- * link_service provides the only entry point to link functions with function
- * pointer style. This header is strictly private in dc and should never be
- * included by DM because it exposes too much dc detail including all dc
- * private types defined in core_types.h. Otherwise it will break DM - DC
- * encapsulation and turn DM into a maintenance nightmare.
- *
- * The following shows a link component relation map.
- *
- * DM to DC:
- * DM includes dc.h
- * dc_link_exports.c or other dc files implement dc.h
- *
- * DC to Link:
- * dc_link_exports.c or other dc files include link.h
- * link_factory.c implements link.h
- *
- * Link sub-component to Link sub-component:
- * link_factory.c includes --> link_xxx.h
- * link_xxx.c implements link_xxx.h
-
- * As you can see if you ever need to add a new dc link function and call it on
- * DM/dc side, it is very difficult because you will need layers of translation.
- * The most appropriate approach to implement new requirements on DM/dc side is
- * to extend or generalize the functionality of existing link function
- * interfaces so minimal modification is needed outside link component to
- * achieve your new requirements. This approach reduces or even eliminates the
- * effort needed outside link component to support a new link feature. This also
- * reduces code discrepancy among DMs to support the same link feature. If we
- * test full code path on one version of DM, and there is no feature specific
- * modification required on other DMs, then we can have higher confidence that
- * the feature will run on other DMs and produce the same result. The following
- * are some good examples to start with:
- *
- * - detect_link --> to add new link detection or capability retrieval routines
- *
- * - validate_mode_timing --> to add new timing validation conditions
- *
- * - set_dpms_on/set_dpms_off --> to include new link enablement sequences
- *
- * If you must add new link functions, you will need to:
- * 1. declare the function pointer here under the suitable commented category.
- * 2. Implement your function in the suitable link_xxx.c file.
- * 3. Assign the function to link_service in link_factory.c
- * 4. NEVER include link_xxx.h headers outside link component.
- * 5. NEVER include link.h on DM side.
