Subject: [PATCH v3 1/7] regulator: dt-bindings: Add system-critical-regulator property

Introduce a new Device Tree property 'system-critical-regulator' for
marking a regulator as crucial for system stability or functionality.
This helps in distinguishing regulators that are vital for system
operations and may require special handling in under-voltage scenarios.
