[PATCH v2 2/4] dt-bindings: pwm: tiehrpwm: Make clock and clock-names as required properties

Driver fails to probe when 'clock' and 'clock-names' properties are not
populated in DT. But the binding documentation says these properties are
optional. Fix this by making 'clock' and 'clock-names' properties as
required.
