The BCM4345C5 of the Orange Pi 3 ships with the controller default address. Fix it up so it can function properly.
The used address is "ethaddr" with the LSB flipped.

NOTE: "local-bd-address" is a universal property, the kernel patch for btbcm to use that is in bluetooth-next.

IIRC someone mentioned before that unlike Ethernet and WiFi, Bluetooth does not have a "locally administered" address space, so any address used could possibly collide with other devices.
