-Microchip USB 2.0 Hi-Speed Hub Controller
-
-The device node for the configuration of a Microchip USB251x/xBi USB 2.0
-Hi-Speed Controller.
-
-Required properties :

-
-Optional properties :
- - reset-gpios : Should specify the gpio for hub reset

- - power-on-time-ms : Specifies the time it takes from the time the host
- initiates the power-on sequence to a port until the port has adequate
- power. The value is given in ms in a 0 - 510 range (default is 100ms).
- - swap-dx-lanes : Specifies the ports which will swap the differential-pair
- (D+/D-), default is not-swapped.

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.
