[PATCH u-boot-marvell 04/16] ddr: marvell: a38x: debug: Define DDR_VIEWER_TOOL variables only if needed, and make them static

["Marek Behún" <kabel@kernel.org>]

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.
