dt-bindings: regulator: add refgen regulator bindings 

Some Qualcomm Technologies, Inc. SoCs such as SDM845 utilize
reference bias generators for various internal PHY blocks.
These are called REFGENs.  Add binding documentation for
REFGEN devices.

Qualcomm Technologies, Inc. REFGEN Regulator



Some Qualcomm Technologies, Inc. SoCs utilize reference bias generators for

various internal PHY blocks.  These are called REFGENs.



Supported properties:

- compatible

	Usage:      required

	Value type: <string>

	Definition: Must be one of: "qcom,refgen-regulator",

		    "qcom,refgen-sdm845-regulator", or

		    "qcom,refgen-kona-regulator".



- reg

	Usage:      required

	Value type: <prop-encoded-array>

	Definition: Address and size of the REFGEN registers.



- regulator-name

	Usage:      required

	Value type: <string>

	Definition: Specifies the name for this REFGEN regulator.



- regulator-enable-ramp-delay

	Usage:      optional

	Value type: <u32>

	Definition: REFGEN enable time in microseconds.



- parent-supply

	Usage:      optional

	Value type: <phandle>

	Definition: phandle to the parent supply/regulator node if one exists.



Example:



refgen-regulator@ff1000 {

	compatible = "qcom,refgen-regulator";

	reg = <0xff1000 0x60>;

	regulator-name = "refgen";

};
