base-files: add board.d support for bridge device

Browse Source 
Latest netifd allows us to setup network bridges with implicit vlan
tagging. For this to work, we need to setup several additional uci
sections. This feature is particularly usefull for DSA tupe devices.
Add board.d and uci-defaults support for generating the sections.
