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 2d44d165e939 ("scsi: lpfc: Convert existing %pf users to %ps")
Depends-on: commit b295c3e39c13 ("tools lib traceevent: Convert remaining %p[fF] users to %p[sS]")
