regulator: Convert SY8106A binding to a schema

The Silergy SY8106A is a regulator controlled through i2c supported by
Linux with a matching device tree binding.

Now that we have the DT validation in place, let's convert the device
tree bindings for that driver over to a YAML schema.

-SY8106A Voltage regulator
-
-Required properties:
-- compatible: Must be "silergy,sy8106a"
-- reg: I2C slave address - must be <0x65>
-- silergy,fixed-microvolt - the voltage when I2C regulating is disabled (set
-  by external resistor like a fixed voltage)
-
-Any property defined as part of the core regulator binding, defined in
-./regulator.txt, can also be used.
-
-Example:
-
-       sy8106a {
-               compatible = "silergy,sy8106a";
-               reg = <0x65>;
