Peter A. Bigot da3f7feaf8 soc: arm: nordic_nrf: unrevert provide custom busy_wait implementations ... This reverts commit bd24b31139. While the test case failure described in #14186 is associated with the cycle-based busy-wait implementation, that test is fragile, and fails less frequently once the incongruence between ticks-per-second and the 32 KiHz RTC clock are resolved. It also assumes that the system clock is more stable than the infrastructure underlying the the busy-wait implementation, which is not necessarily true. The gross inaccuracies in the standard busy-wait on Nordic described in issue #11626 justify restoring the custom solution. As this applies to all Nordic devices, move the setting to the top-level Kconfig.defconfig.
