regulator: da9210: add Device Tree support 



This patch adds basic Device Tree support to the da9210 regulator driver -
with no special properties, since also driver's platform data only contains
standard regulator initialisation parameters.

* Dialog Semiconductor DA9210 Voltage Regulator



Required properties:



- compatible:	must be "diasemi,da9210"

- reg:		the i2c slave address of the regulator. It should be 0x68.



Any standard regulator properties can be used to configure the single da9210

DCDC.



Example:



	da9210@68 {

		compatible = "diasemi,da9210";

		reg = <0x68>;



		regulator-min-microvolt = <900000>;

		regulator-max-microvolt = <1000000>;

		regulator-boot-on;

		regulator-always-on;

	};
