mfd: sec: Add clock cell for s2mps11

- interrupts: Interrupt specifiers for interrupt sources.

Optional nodes:

- clocks: s2mps11 provides three(AP/CP/BT) buffered 32.768 KHz outputs, so to

  register these as clocks with common clock framework instantiate a sub-node

  named "clocks". It uses the common clock binding documented in :

  [Documentation/devicetree/bindings/clock/clock-bindings.txt]

  - #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.

    Clock               ID

    ----------------------

    32KhzAP		0

    32KhzCP		1

    32KhzBT		2

- regulators: The regulators of s2mps11 that have to be instantiated should be

included in a sub-node named 'regulators'. Regulator nodes included in this

sub-node should be of the format as listed below.

		compatible = "samsung,s2mps11-pmic";

		reg = <0x66>;

		s2m_osc: clocks{

			#clock-cells = 1;

			clock-output-names = "xx", "yy", "zz";

		};

		regulators {

			ldo1_reg: LDO1 {

				regulator-name = "VDD_ABB_3.3V";

static struct mfd_cell s2mps11_devs[] = {

	{

		.name = "s2mps11-pmic",

	},

	}, {

		.name = "s2mps11-clk",

	}

};
