Subject: [PATCH 07/12] drm/amd/display: Remove unused value0 variable

Remove the variable value0 from the function
dcn10_link_encoder_update_mst_stream_allocation_table.

This was pointed by clang with the following warning:

drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_link_encoder.c:1223:11:
warning: variable 'value0' set but not used [-Wunused-but-set-variable]
        uint32_t value0 = 0;
                 ^
1 warning generated.
