Samsung DeviceTree update for v4.11: 1. Fixes for initial audio clocks configuration. 2. Enable sound on Odroid-X board. 3. Enable DMA for UART modules on Exynos5 SoCs. 4. Add CPU OPPs for Exynos4412 Prime (newer version of Exynos4412). This pulls necessary change in the clocks. 5. Remove Exynos4212. We do not have any mainline boards with it. This will simplify few bits later.
