tracing: Extract duplicate ftrace_raw_init_event_foo()

Browse Source 
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.
