Subject: [PATCH 1/5] dt-bindings: net: Add generic Bluetooth controller

Bluetooth controllers share the common local-bd-address property.
Add a generic YAML schema to replace bluetooth.txt for those.

Signed-off-by: Sven Peter <sven@...npeter.dev>

I hope it's fine to list the current Bluetooth maintainers in here
as well.
