base-files: allow setting device and bridge macs

Browse source 
Add code for setting mac addresses inside board.json and rendering
them out to uci. On switches we want to have a unique MAC on each port.
With 48 port switches that would require 48 device sections in
/etc/config/network. Doing so via board.json is easier.
