printk: synchronize %p formatting documentation
Move all pointer-formatting documentation to one place in the code and one
place in the documentation instead of keeping it in three places with
different level of completeness. Documentation/printk-formats.txt has
detailed information about each modifier, docstring above pointer() has
short descriptions of them (as that is the function dealing with %p) and
docstring above vsprintf() is removed as redundant. Both docstrings in
the code that were modified are updated with a reminder of updating the
documentation upon any further change.
