This reverts commit fd8ca83e9a.
https://github.com/zephyrproject-rtos/zephyr/pull/69705
Introduced a regression in main in which
tests/subsys/logging/log_timestamp
started failing. (See
https://github.com/zephyrproject-rtos/zephyr/issues/72344
for more info).
Let's revert the PR. It can be submitted after with the issue
fixed.
