[why]
link component should only have one interface serving dc.
[how]
We are moving dc_link functions exposed to DM to dc_link_exports
and unify link component interface in link.h with function pointer
to match the style of other dc component. This is the second step to move
dc_link functions under link root folder to dc_link_exports.
