The splash screen loading code can be reused by other compulab boards. For now extract it to a common location for further reuse. This also switches the splash code dependency from CONFIG_LCD to CONFIG_SPLASH_SCREEN as it should normally be. In addition this patch fixes the accidental dependency of the get_board_mem_timings() function on CONFIG_LCD, by just moving the splash code and leaving the above function intact.
