Subject: [PATCH 19/40] drm/amd/display/dc/bios/command_table: Remove unused variable

None of the surrounding code was removed just in case even a small
fraction of it was functional.

Fixes the following W=1 kernel build warning(s):

 drivers/gpu/drm/amd/amdgpu/../display/dc/bios/command_table.c: In function ‘adjust_display_pll_v2’:
 drivers/gpu/drm/amd/amdgpu/../display/dc/bios/command_table.c:1459:35: warning: variable ‘params’ set but not used [-Wunused-but-set-variable]
