Subject: [PATCH 1/4] ARM: multi_v7_defconfig: Enable CPU idle for Exynos

From: Krzysztof Kozlowski <k.kozlowski@...sung.com>

Current Exynos CPU idle driver supports entering AFTR (Arm Off, Top
Running) mode on Exynos3250, Exynos4210 (coupled), Exynos4x12 and
Exynos5250. Enable it in default configuration to reduce energy
consumption.
