IPC interfaces binding

All the functions of this API are provided by the modemService app.

The RING pin can be configured to notify a host device with different timing of pulse signals for different module activities.

le_riPin_AmIOwnerOfRingSignal() function checks whether the application core is the current owner of the Ring Indicator signal.
le_riPin_TakeRingSignal() function takes control of the Ring Indicator signal.
le_riPin_ReleaseRingSignal() function releases control of the Ring Indicator signal.
le_riPin_PulseRingSignal() function sets the ring signal high for configurable duration of time before lowering it.
