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;
};
