base-files: add a hardware detection layer
this allows targets to use the new uci-default helper which will generate a file called /etc/board.json. a tool called /bin/config_generate can then be used to generate the default uci settings. Signed-off-by: John Crispin <blogic@openwrt.org> SVN-Revision: 42185
