Description
### Description
The reset requests to pwrmgr go through aon clk synchronizers. This seems problematic for escalation resets, given they are more security critical, since it leaves a window of hundreds of cycles after the escalation cause when the cpu remains active.
Below there is a proposed way to block cpu fetching, and this issue will require two items:
- [ ] Add support to disable cpu fetch upon escalation request reception
- [ ] Add unit test for this feature
