lib/vsprintf: Remove support for %pF and %pf in favour of %pS and %ps

%pS and %ps are now the preferred conversion specifiers to print function
names. The functionality is equivalent; remove the old, deprecated %pF
and %pf support.

Depends-on: commit 2d44d165e9 ("scsi: lpfc: Convert existing %pf users to %ps")
Depends-on: commit b295c3e39c ("tools lib traceevent: Convert remaining %p[fF] users to %p[sS]")

@ -97,14 +95,6 @@ The ``S`` and ``s`` specifiers are used for printing a pointer in symbolic
format. They result in the symbol name with (S) or without (s)
offsets. If KALLSYMS are disabled then the symbol address is printed instead.
Note, that the ``F`` and ``f`` specifiers are identical to ``S`` (``s``)
and thus deprecated. We have ``F`` and ``f`` because on ia64, ppc64 and
parisc64 function pointers are indirect and, in fact, are function
descriptors, which require additional dereferencing before we can lookup
the symbol. As of now, ``S`` and ``s`` perform dereferencing on those
platforms (when needed), so ``F`` and ``f`` exist for compatibility
reasons only.
The ``B`` specifier results in the symbol name with offsets and should be
used when printing stack backtraces. The specifier takes into
consideration the effect of compiler optimisations which may occur
