Subject: [PATCH v3 2/2] dt-bindings: ARM: Mediatek: add interrupt as required properties to the mt6397/mt6323 doc

MT6397/MT6323 have one interrupt line connected to the main SoC.
Interrupt should be required feature of pmic, each sub module also
need it to complete their function or error detect, add it as
required properties on dts file.
