Subject: [PATCH AUTOSEL 5.4 28/33] Bluetooth: btbcm: Use the BDADDR_PROPERTY quirk

From: Andre Heider <a.heider@...il.com>

[ Upstream commit a4f95f31a9f38d9bb1fd313fcc2d0c0d48116ee3 ]

Some devices ship with the controller default address, like the
Orange Pi 3 (BCM4345C5).

Allow the bootloader to set a valid address through the device tree.
