ARM: dts: exynos: Move common Exynos5410/542x/5800 nodes to new DTSI
The Exynos5410/542x/5800 are very similar designs. Create a new DTSI with common nodes to remove DTS duplication. Although currently only MCT and SysRAM are shared but in future more nodes will be added to the common file. The patch should not have functional impact.
