* clarify effects of lfclk selection

As per Softdevice changelog "Synthesized low frequency clock source is not tested or intended for use with BLE stack."
Also https://devzone.nordicsemi.com/question/953/what-low-frequency-clock-sources-can-i-use/?answer=955#post-id-955
Maybe option should better be removed?
