[PATCH 2/2] Raspberry Pi: Copy Bluetooth device address in DT

[Fiona Klute]

The firmware sets local-bd-address, copy it when loading a new DT.

This simple copy works with upstream Linux DT, and with the downstream
RPi one as long as BT has not been moved to mini-UART. The downstream
DT additionally defines /aliases/bluetooth, which is updated by the
matching overlays. A more generic (but also more complex) approach
would be to *try* using /aliases/bluetooth, and fall back to the fixed
path if it's undefined. If that's preferred I'm happy to update the
patch.
