Samsung DTS ARM changes for v5.10 1. Add sound support to Galaxy S3/Midas family (Exynos4412). 2. Add sound support to Galaxy S/Aries family (S5Pv210). 3. Configure L2C-310 cache controller via DTS on Exynos4. 4. Big cleanup of Exynos DTS to fix as many dtschema warnings as possible. This includes adding missing properties (thus e.g. enabling S3C RTC clock), correcting existing nodes, renaming of nodes and using non-deprecated properties or compatibles. Except mentioned bring up of S3C RTC, this should not have visible effect.
