tracing: Extract duplicate ftrace_raw_init_event_foo()
Use a generic trace_event_raw_init() function for all event's raw_init callbacks (but kprobes) instead of defining the same version for each of these. This shrinks the kernel code: text data bss dec hex filename 5355293 1961928 7103260 14420481 dc0a01 vmlinux.o.old 5346802 1961864 7103260 14411926 dbe896 vmlinux.o raw_init can't be removed, because ftrace events and kprobe events use different raw_init callbacks. Though it's possible to totally remove raw_init, I choose to leave it as it is for now.
