ARM: exynos_defconfig: Enable SCHED_MC and ENERGY_MODEL
The Energy Model (EM) is needed to run Energy Aware Scheduler (EAS). Enable ENERGY_MODEL to make that happen. This will increase energy efficiency of the big.LITTLE platforms (e.g. Exynos5422) by smarter decisions in scheduling tasks in non-heavy workloads. Add SCHED_MC in order to create another level in scheduling domains: 'MC'. This improves scheduler's decisions on platforms with CPU clusters, such as big.LITTLE.
