ARM: dts: exynos: Add DMC device to Exynos5422 and Odroid XU3-family boards
Add description of Dynamic Memory Controller and PPMU counters to Exynos5422 and Odroid XU3/XU4/HC1 boards. They are used by exynos5422-dmc driver. There is a definition of the memory chip, which is then used during calculation of timings for each OPP. The algorithm in the driver needs these two sets to bound the timings.
