Andy Ross 7aae75bd1c idle: Fix tickless timeout behavior ... If the idle code was detecting that it needed to sleep for less than CONFIG_SYS_TICKLESS_IDLE_THRESH, then it would never call z_clock_set_timeout() at all, which means that the system would never wake up unless it already had a timeout scheduled! Apparently we lacked a test case to detect this condition. Honestly this seems like a crazy feature to me. There's no benefit in delivering needless tick announcements. If the system has the capacity to enter deeper sleep for long timeouts, that's already exposed via the PM APIs, the timer subsystem needn't be involved. But... we actually have a test (tickless_concept) that looks at this, so support it for now and consider deprecation later.
