Enable use of __disable_irq() to disable Zero Latency IRQs to prevent
|

higher priority contexts (including ZLIs) that might preempt the

handler and call nrf_rtc_timer API from destroying the internal state

in nrf_rtc_timer.

When enabled, a function can be used to trigger RTC overflow and

effectively shift time into the future.
