We have a module called 'board'. Sometimes buildman uses 'brd' as an instance variable but sometimes it uses 'board', which is confusing and can mess with the module handling. Update the code to use 'brd' consistently, making it easier for tools to determine when the module is being referenced. Signed-off-by: Simon Glass <sjg@chromium.org>
