>     wctdm24xxp: Use time interval for debouncing FXO ring detect.
>     
>     Do not assume the ring detection function is called for every frame.
>     Also change the debounce logic to a state machine to clarify what state
>     a port is in and unify the technique for debouncing the various signals.
