clk: exynos5250: register clocks using common clock framework

The Exynos5250 clocks are statically listed and registered using the
Samsung specific common clock helper functions. Both device tree based
clock lookup and clkdev based clock lookups are supported.

* Samsung Exynos5250 Clock Controller
The Exynos5250 clock controller generates and supplies clock to various
controllers within the Exynos5250 SoC.
Required Properties:
- comptible: should be one of the following.
- "samsung,exynos5250-clock" - controller compatible with Exynos5250 SoC.
- reg: physical base address of the controller and length of memory mapped
region.
- #clock-cells: should be 1.
The following is the list of clocks generated by the controller. Each clock is
assigned an identifier and client nodes use this identifier to specify the
clock which they consume.

Example 1: An example of a clock controller node is listed below.
clock: clock-controller@0x10010000 {
compatible = "samsung,exynos5250-clock";
reg = <0x10010000 0x30000>;
#clock-cells = <1>;
};
Example 2: UART controller node that consumes the clock generated by the clock
controller. Refer to the standard clock bindings for information
about 'clocks' and 'clock-names' property.
serial@13820000 {
compatible = "samsung,exynos4210-uart";
reg = <0x13820000 0x100>;
interrupts = <0 54 0>;
clocks = <&clock 314>, <&clock 153>;
clock-names = "uart", "clk_uart_baud0";
};
