Reported by Vinayak Kariappa Chettimada:

nRF5x Series: System Clock driver using NRF_RTC.

As an OS kernel i want a low power system clock driver using a dedicated RTC on nRFx series so that i can have time awareness while the kernel sleeps during cpu idle.

SysTick on nRF5x Series are absent or off during CPU sleep, hence the kernel should use NRF_TIMER (high current consumption) or NRF_RTCx (low power low precision) as system clock.
