Subject: [PATCH v2 3/5] dt-bindings: watchdog: separate out the IPQ5424
 compatilble

To retrieve the system restart reason code from IMEM, need to define the
certain device specific data. To achieve that, decouple the IPQ5424
compatible from the existing list and define along with 'qcom,kpss-wdt'.
