Subject: [PATCH v6 1/7] power: Extend power_on_reason.h for upcoming PSCRR framework

Prepare for the introduction of the Power State Change Reason Recorder
(PSCRR)  framework by expanding the power_on_reason.h header. This
extension includes new power-on reasons:
- POWER_ON_REASON_OVER_CURRENT for over-current conditions.
- POWER_ON_REASON_REGULATOR_FAILURE for regulator failures.
- POWER_ON_REASON_OVER_TEMPERATURE for over temperature situations.
- POWER_ON_REASON_EC_PANIC for EC panics

changes v6:
- add POWER_ON_REASON_EC_PANIC
