dt-bindings: usb: cypress,hx3: Add support for all variants

The Cypress HX3 hubs use different default PID value depending
on the variant. Update compatibles list.
Becasuse all hub variants use the same driver data, allow the
dt node to have two compatibles: leftmost which matches the HW
exactly, and the second one as fallback.
