ARM: dts: exynos: Add interrupts to DMC controller in Exynos5422

Browse Source 
Add interrupts to Dynamic Memory Controller in Exynos5422 and Odroid
XU3-family boards. It will be used instead of devfreq polling mode
governor. The interrupt is connected to performance counters private
for DMC, which might track utilisation of the memory channels.
