checkpatch: use a list of "link" tags
The following commit will allow the use of a similar "link" tag. Because there is a possibility that other similar tags will be added in the future and to reduce the number of places where the code will be modified to allow this new tag, a list with all these "link" tags is now used. Two variables are created from it: one to search for such tags and one to print all tags in a warning message.
