It depends.
If the existing users use a *really* reasonable name for the property
and use the same format it could be an option to add it to the lookup
besides 'local-bd-address', similar to what fwnode_get_mac_address()
does.
If the existing users populate a custom property with the BD address
in the bootloader you could roll out a bootloader change. You'd have
to make sure that bootloader and kernel match. The bootloader could
still populate the custom property to be compatible with 'old'
kernels.
