dt-bindings: usb: Add the binding example for the Genesys Logic GL3523 hub
Add the binding example for the USB3.1 Genesys Logic GL3523
integrates with USB 3.1 Gen 1 Super Speed and USB 2.0 High-Speed
hub.
For onboard hub controllers that support USB 3.x and USB 2.0 hubs
with shared resets and power supplies, this property is used to identify
the hubs with which these are shared.
GL3523 has built-in 5V to 3.3V and 5V to 1.2V regulators, which serves
power to the USB HUB, it uses 5V power regulator.
Update the peer-hub description.
