dt-bindings: usb: Add binding for Cypress HX3 USB 3.0 family
The HX3 family comes in different variants (up to 4 USB 3.0 ports;
multi-TT), e.g. CYUSB330x/CYUSB331x/CYUSB332x/CYUSB230x.
This initial version of the binding only describes USB related aspects
of the HX3 family, it does not cover the option of connecting the
controller as an i2c slave.
