Subject: [PATCH v2 2/5] 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.

Fixes: 1eca51f58a10 ("dt-bindings: usb: Add binding for Cypress HX3 USB 3.0 family")
Cc: stable@...r.kernel.org # 6.6
Cc: stable@...r.kernel.org # Backport of the patch ("dt-bindings: usb: usb-device: relax compatible pattern to a contains") from list: https://lore.kernel.org/linux-usb/20250418-dt-binding-usb-device-compatibles-v2-1-b3029f14e800@cherry.de/
Cc: stable@...r.kernel.org # Backport of the patch in this series fixing product ID in onboard_dev_id_table in drivers/usb/misc/onboard_usb_dev.c driver
