Bluetooth: btbcm: add default address for BCM43430A1

Browse Source 
The BCM43430A1 has a default MAC address of AA:AA:AA:AA:AA:AA.
Although, unlike some other entries, this does not include the
chip name, it is clearly not a real address. This was found in
AzureWave AW-NB197SM and AW-NM372SM modules.
