clk: exynos4: register clocks using common clock framework

Browse Source 
The Exynos4 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 Exynos4 Clock Controller
The Exynos4 clock controller generates and supplies clock to various controllers
within the Exynos4 SoC. The clock binding described here is applicable to all
SoC's in the Exynos4 family.
Required Properties:
- comptible: should be one of the following.
- "samsung,exynos4210-clock" - controller compatible with Exynos4210 SoC.
- "samsung,exynos4412-clock" - controller compatible with Exynos4412 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. Some of the clocks are available only on a particular
Exynos4 SoC and this is specified where applicable.

Example 1: An example of a clock controller node is listed below.
clock: clock-controller@0x10030000 {
compatible = "samsung,exynos4210-clock";
reg = <0x10030000 0x20000>;
#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";
};
