    This patch just removes '.' character from the sysfs name of devfreq-event
    device as following. Usually, the subsystem uses the similiar naming style
    such as {framework name}{Number}.
    - old : /sys/class/devfreq-event/event.(X)
    - new : /sys/class/devfreq-event/event(X)
    
    And this patch initializes the value of 'event_no' with -1
    in order to remove the unneeded operation (-1) when calling
    the atomic_inc_return(&event_no).
    
    Lastly, this patch adds the ABI document for devfreq-event class.
