Krzysztof Chruscinski 482fae74a8 drivers: timer: nrf_rtc_timer: Fix race condition 
RTC interrupt was reading CC value and passing it to the handler.
However, higher priority interrupt could preempt RTC interrupt
and set new CC value. In that case CC value read in the RTC
interrupt context was not the one that triggered the interrupt.
Added fallback to COUNTER value if that case is detected.

Using COUNTER is not as precise as CC because it returns time
when event was handled and not when event occured but it is the
only option since CC value is overwritten.
