dt-bindings: clock: at91: new sckc bindings 



Remove the need for child nodes in the sckc binding to be able to remove
dtc warnings and have a more modern binding.

Also document optional properties.

Required properties:

- compatible : shall be one of the following:

	"atmel,at91sam9x5-sckc" or

	"atmel,at91sam9x5-sckc",

	"atmel,sama5d3-sckc" or

		at91 SCKC (Slow Clock Controller)

		This node contains the slow clock definitions.



	"atmel,at91sam9x5-clk-slow-osc":

		at91 slow oscillator



	"atmel,at91sam9x5-clk-slow-rc-osc":

		at91 internal slow RC oscillator

- reg : defines the IO memory reserved for the SCKC.

- #size-cells : shall be 0 (reg is used to encode clk id).

- #address-cells : shall be 1 (reg is used to encode clk id).

- #clock-cells : shall be 0.

- clocks : shall be the input parent clock phandle for the clock.



Optional properties:

- atmel,osc-bypass : boolean property. Set this when a clock signal is directly

  provided on XIN.



For example:

	sckc: sckc@fffffe50 {

		compatible = "atmel,sama5d3-pmc";

		reg = <0xfffffe50 0x4>

		#size-cells = <0>;

		#address-cells = <1>;



		/* put at91 slow clocks here */

	sckc@fffffe50 {

		compatible = "atmel,at91sam9x5-sckc";

		reg = <0xfffffe50 0x4>;

		clocks = <&slow_xtal>;

		#clock-cells = <0>;
