[PATCH 32/37] drm/amd/display/dc/link/protocols/link_dp_capability: Remove unused variable and mark another as __maybe_unused

[Lee Jones]

‘ds_port’ is clearly not used anywhere and ‘result_write_min_hblank’ is
only utilised when debugging is enabled.  The alternative would be to
allocate the variable under the same clause as the debugging code, but
that would become very messy, very quickly.

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

 drivers/gpu/drm/amd/amdgpu/../display/dc/link/protocols/link_dp_capability.c: In function ‘dp_wa_power_up_0010FA’:
 drivers/gpu/drm/amd/amdgpu/../display/dc/link/protocols/link_dp_capability.c:280:42: warning: variable ‘ds_port’ set but not used [-Wunused-but-set-variable]
