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.

How come there's no fallback here? Looking at the binding patch there's
no device-specific handling done, what's incompatibly different between
this device and some of the other ones supported by the hci_bcm driver?
