General issue report

On release/5.5 (and likely other branches) I cannot disable PM_SLP_IRAM_OPT for esp32s3.
The reason is, that the option is always automatically selected by PM_SLEEP_FUNC_IN_IRAM (which is only editable on esp32c2).

I am not using power management and I am not using light sleep. I want to have more free RAM instead.
