Add a stub s_init function in the board file. The reason why the stub function is needed is that most of the work is now being done in board_init_f(), there is no need for the SPL to do anything s_init(). However, since lowlevel_init() is still branching to s_init(), we need stub function for now, until lowlevel_init() morphs into s_init(). Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com>
