Cannot change back the CPU frequency

[tdabasinskas]

I prefer not to go into detail regarding my observations and the test cases I used to reproduce this issue, as I believe it could be security-sensitive. Additionally, it is unclear whether this bug is limited to CPU frequency adjustments or if it represents a broader flaw affecting other device-mode restricted settings. I have not investigated further, as repeatedly cycling device modes via the mode/reset button is not practical for extended testing.
