[PATCH 3/3] drm/amd/display: remove unused variables in dcn21_set_backlight_level

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

The only references to these variables were removed, so they now cause
warnings and have to be removed as well:

drivers/gpu/drm/amd/amdgpu/../display/dc/dcn21/dcn21_hwseq.c:226:20: error: unused variable 'cmd' [-Werror,-Wunused-variable]
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn21/dcn21_hwseq.c:229:11: error: unused variable 'otg_inst' [-Werror,-Wunused-variable]

Fixes: 6f0ef80a00ad ("drm/amd/display: Fix ABM pipe/backlight issues when change backlight")
