drm/amd/display: remove set but not used variable 'pixel_width'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/amd/display/dc/dcn10/dcn10_dpp.c:137:11: warning: variable ‘pixel_width’ set but not used [-Wunused-but-set-variable]

It is introduced by commit 70ccab604049 ("drm/amdgpu/display:
Add core dc support for DCN"), but never used, so remove it.
