Kernel scheduler tests fail on Smartbond due to oscillator calibration #99501
Description
Describe the bug
Kernel scheduler tests (schedul_api) does not expect any other thread to be actively running during test.
For Smartbond tests fail due to execution automatic calibration works that are periodically measuring oscillators frequencies.
It seems reasonable to have option to disable calibration background works for specific tests.
Regression
- This is a regression.
Steps to reproduce
west build -b da1469x_dk_pro/da14699 tests/kernel/sched/schedule_api/kernel.schedulerflash and observer test output on console
