bluetooth-init: get the BT MAC address from the DT node 

Retrieve the Bluetooth MAC address from the device tree (DT) node
rather than from the environment.
U-Boot will populate this address by default, but it can be
overridden with a custom MAC address specified directly in the DT,
which then takes priority.
