This patch adds an option to skip the registration of LCD stdio ouput for boards that want to show different text on LCD than on serial output (or the active stdout selected by the environment variable).

This implementation is similar to what has been added to cfb_console.c by Stefan Roese sr@denx.de per commit 6cc7ba9e on 05/15/2009
