hrtimers: Update formatting of documentation

Documentation of functions lacks the annotations which are used by
kernel-doc and *.rst to make appearance in rendered documents more
user-friendly.

Use those annotations to improve user-friendliness. While at it prevent
duplication of comments and use a reference instead.
