math64: favor kernel-doc from header files 

Fix the kernel-doc markings for div64 functions to point to the header
file instead of the lib/ directory.  This avoids having implementation
specific comments in generic documentation.  Furthermore, given that
some kernel-doc comments are identical, drop them from lib/math64 and
only keep there comments that add implementation details.
