arm: sunxi: add a config option to fixup a Bluetooth address

Browse Source 
Some Bluetooth controllers, like the BCM4345C5 of the Orange Pi 3,
ship with the controller default address.

Add a config option to fix it up so it can function properly.

This option specifies the DT compatible name of the Bluetooth
controller for which to set the "local-bd-address" property.
Set this option if your device ships with the Bluetooth controller
default address.
The used address is "bdaddr" if set, and "ethaddr" with the LSB
flipped elsewise.
