Add print_fmt field and the initialization codes.
It will be used for replacing ->show_format().

This change log is very lacking. I don't even know what this patch is
doing. I'm guessing other patches will depend on it. But this patch
alone should have a change log that describes the goal that will happen
to give it rational.
If I'm bisecting the kernel and I come across this change, I want the
change log to explain why this change exists, and not have to spend time
searching the logs for other patches that may depend on this one.

print fmt: "irq=%d name=%s", REC->irq, __get_str(name)
C) ========> string "print fmt: " and the print format after it.
How my patches work:
For B)
Ensure all fields are add into struct ftrace_event_call->fields. (patch#4)
Ensure all fields are correct. (patch#5)
For C)
add a print_fmt field (this patch)
init print_fmt carefully (this patch and patch#7 patch#8)
So when we generate format file:
print name
print ID
print string "format:"
use struct ftrace_event_call->fields to print fields
use struct ftrace_event_call->print_fmt to print "print fmt: XXXXXXXXXXX"
Thanks

Adds print_fmt field to struct ftrace_event_call
and some initialization code. But this field is not used now,
the next patches will use it and replace the ->show_format().
It is preparing patch for new way of printing format files which
uses defined fields and a defined print_fmt to print formats.
How will the new way works(and how print_fmt will be used)?
print name
print ID
print string "format:"
use struct ftrace_event_call->fields to print fields
use struct ftrace_event_call->print_fmt to print "print fmt: XXXXXXXXXXX"

tracing: Add print_fmt field
This is part of a patch set that removes the show_format method
in the ftrace event macros.
The print_fmt field is added to hold the string that shows
the print_fmt in the event format files. This patch only adds
the field but it is currently not used. Later patches will use
this field to enable us to remove the show_format field
and function.
