On 32 bits platforms, timer_get_us() returns an unsigned long which
is a 32 bits. timer_get_us() wraps around every 72 minutes
(2 ^ 32 / 1000000 =~ 4295 sec =~ 72 min).
So the test "if time_after_eq64(now, cyclic->next_call)" is no more
true when cyclic->next_call becomes above 32 bits max value (4294967295).
At this point after 72 min, no more cyclic function are
executed included watchdog one.
Instead of using timer_get_us(), use get_timer_us() which returns a
uint64_t, this allows a rollover every 584942 years.
