Bluetooth: btbcm: Add default address for BCM2076B1
BCM2076B1 appears to use 20:76:A0:00:56:79 as default address. This address is used by at least 5 devices with the AMPAK AP6476 module and is also suspicious because it starts with the chip name 2076 (followed by a different revision A0 for some reason). Add it to the list of default addresses and leave it up to the user to configure a valid one. Signed-off-by: Stephan Gerhold <stephan@gerhold.net> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
