Changes since V8:
        1.sata@122f0000 and sata_phy@12170000 disabled by default in 
          SOC specific dts file and enabled the same in board dts file.

Changes since V7:
        1.syscon-phandle name updated.

Changes since V6:none

Changes since V5:none

Changes since V4:
        1.Used the new phandle "sata_phy_i2c" in the DT entry. 
        2.Updated binding document.

Changes since V3:
        1.Moved the binding info to the /bindings/phy/

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.
