[PATCH v3 10/16] checkpatch: Remove links to outdated documentation

[Anna-Maria Behnsen]

checkpatch.pl checks for several things related to sleep and delay
functions. In all warnings the outdated documentation is referenced. Also
in checkpatch kernel documentation the outdated documentation is
referenced.

Replace the links to the outdated documentation with links to the function
description.

Note: Update of the outdated checkpatch checks is done in a second step.
