Devicetree naming convention requires device node names to use hyphens instead of underscore, so Exynos5422 devfreq event name "ppmu-event3-dmc0_0" should be "ppmu-event3-dmc0-0". Newly introduced dtschema enforces this, however the driver still expects old name with an underscore. Add new events for Exynos5422 while still accepting old name for backwards compatibility.
