Add new callback operations for a dpll device: - freq_monitor_get(..) - to obtain current state of frequency monitor feature from dpll device, - freq_monitor_set(..) - to allow feature configuration. Add new callback operation for a dpll pin: - measured_freq_get(..) - to obtain the measured frequency in mHz. Obtain the feature state value using the get callback and provide it to the user if the device driver implements callbacks. The measured_freq_get pin callback is only invoked when the frequency monitor is enabled. The freq_monitor_get device callback is required when measured_freq_get is provided by the driver. Execute the set callback upon user requests.
