[PATCH 1/3] ARM: dts: exynos: Add interrupt to DMC controller in Exynos5422

[Lukasz Luba]

Add interrupt 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.
