The variables is_validate_window_per_if, is_validate_window_per_pup, sweep_cnt and is_run_leveling_sweep_tests are only used if DDR_VIEWER_TOOL macro is defined, so define them only in that case. Make them static since they are only used in ddr3_debug.c. Signed-off-by: Marek Behún <kabel@kernel.org>
