This patch adds dt entry for ahci sata controller and its corresponding phy controller.phy node has been added w.r.t new generic phy framework. Changes since V2: 1.Used syscon interface to PMU handling. 2.Changed "sata-phy-i2c" to "exynos-sataphy-i2c". Changes since V1: 1.Minor changes to node name convention. 2.Updated binding document.
