usb: onboard-hub: Add support for Cypress HX3 family
The HX3 is a family of USB3.0 hub controllers that comes in
different variants: CYUSB330x/CYUSB331x/CYUSB332x/CYUSB230x.
To support this hub, controlling of reset pin and two
power supplies is required.
The reset time is set to 10ms, based on the datasheet [1].
Power-on delay time is not required, so it is set to 0.
The compatible strings added to of_match table are
compliant with usb/cypress,hx3.yaml bindings.
