Change timer registration macros (TIMER_OF_DECLARE() and
CLOCKSOURCE_OF_DECLARE()) by adding a new argument. This new argument
is a pointer to an object of type struct timer_of and is used in
timer_probe(). Based on the flags filled in the struct timer_of object
the probing process will parse different DT bindings. Later on the
drivers will use the result of this parsing. Even at the moment only
few drivers are using this functionality there are other that could
be converted to use it.
