The Exynos5440 is not actively developed, there are no development
boards available and probably there are no real products with it.
Remove wide-tree support for Exynos5440.

-* Samsung Exynos5440 Clock Controller
-
-The Exynos5440 clock controller generates and supplies clock to various
-controllers within the Exynos5440 SoC.
-
-Required Properties:
-
-- compatible: should be "samsung,exynos5440-clock".
-
-- reg: physical base address of the controller and length of memory mapped
- region.
-
-- #clock-cells: should be 1.
-
-Each clock is assigned an identifier and client nodes can use this identifier
-to specify the clock which they consume.
-
-All available clocks are defined as preprocessor macros in
-dt-bindings/clock/exynos5440.h header and can be used in device
-tree sources.
-
-Example: An example of a clock controller node is listed below.
-
- clock: clock-controller@10010000 {
- compatible = "samsung,exynos5440-clock";
- reg = <0x160000 0x10000>;
- #clock-cells = <1>;
- };
