Subject: [PATCH v3 6/7] regulator: dt-bindings: Add regulator-uv-survival-time-ms property

Introduce a new Device Tree property 'regulator-uv-survival-time-ms' to
specify the survival time post a critical under-voltage event. This
property defines the time in milliseconds the system can operate before
the on-board capacitors fail, providing a window for necessary actions
or preparations to be taken before power loss, aligning with the
under-voltage event handling mechanism.
