Johan Hovold 179c4acd55 dt-bindings: watchdog: qcom,pm8916-wdt: add parent spmi node to example
The PM8916 watchdog is part of an SPMI PMIC, which lives on an SPMI bus.

Add a parent SPMI bus node with an '#address-cells' of 2 and
'#size-cells' of 0 instead of relying on the fact that the default
number of register cells happen to match (i.e. 1 + 1).
