ARM: SoC: late cleanups 

These could not be part of the first cleanup branch, because they either
 came too late in the cycle, or they have dependencies on other branches.
 Important changes are:
 
 * The integrator platform is almost multiplatform capable after
   some reorganization (Linus Walleij)
 * Minor cleanups on Zynq (Michal Simek)
 * Lots of changes for Exynos and other Samsung platforms, including
   further preparations for multiplatform support and the clocks bindings
   are rearranged.

Samsung SATA PHY Controller
---------------------------
SATA PHY nodes are defined to describe on-chip SATA Physical layer controllers.
Each SATA PHY controller should have its own node.
Required properties:
- compatible : compatible list, contains "samsung,exynos5250-sata-phy"
- reg : offset and length of the SATA PHY register set;
- #phy-cells : must be zero
- clocks : must be exactly one entry
- clock-names : must be "sata_phyctrl"
- samsung,exynos-sataphy-i2c-phandle : a phandle to the I2C device, no arguments
- samsung,syscon-phandle : a phandle to the PMU system controller, no arguments
Example:
sata_phy: sata-phy@12170000 {
compatible = "samsung,exynos5250-sata-phy";
reg = <0x12170000 0x1ff>;
clocks = <&clock 287>;
clock-names = "sata_phyctrl";
#phy-cells = <0>;
samsung,exynos-sataphy-i2c-phandle = <&sata_phy_i2c>;
samsung,syscon-phandle = <&pmu_syscon>;
};
Device-Tree bindings for sataphy i2c client driver
--------------------------------------------------
Required properties:
compatible: Should be "samsung,exynos-sataphy-i2c"
- reg: I2C address of the sataphy i2c device.
Example:
sata_phy_i2c:sata-phy@38 {
compatible = "samsung,exynos-sataphy-i2c";
reg = <0x38>;
