Subject: [bluetooth-next PATCH v3] dt-bindings: net: broadcom-bluetooth: Add CYW43439 DT binding

CYW43439 is a Wi-Fi + Bluetooth combo device from Infineon.
The Bluetooth part is capable of Bluetooth 5.2 BR/EDR/LE .
This chip is present e.g. on muRata 1YN module.

Extend the binding with its DT compatible using fallback
compatible string to "brcm,bcm4329-bt" which seems to be
the oldest compatible device. This should also prevent the
growth of compatible string tables in drivers. The existing
block of compatible strings is retained.
