ea32cd9113 dt-bindings: usb: usb251xb: support usage case without I2C control 
Currently, the usb251xb assumes i2c control, but from HW point of
view, the hub supports usage case without any i2c control, I.E we
only want the gpio controls, for example the following dt node:

usb-hub {
	compatible = "microchip,usb2512b";
	reset-gpios = <&porta 8 GPIO_ACTIVE_LOW>;
};

Modify the dt-binding of usb2512b to support this usage case, and add
the usage example to the examples section.

4a680fcd60 dt-bindings: usb: usb251xb: correct swap-dx-lanes type to uint32 
The "swap-dx-lanes" was never described as uint8 in original TXT
bindings and Linux driver expects uint32.  Fix the type to match Linux
driver expectation.

fff61d4ccf dt-bindings: usb: usb251xb: Convert to YAML schema 
Convert the usb251xb hub DT bindings from text to yaml schema so it is
possible to validate DTs against the schema.

Adjust the example to describe two different hubs at different I2C bus
addresses, to avoid I2C address collission in the example.
