Clang warns:

drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:5089:60: warning: suggest braces around initialization of subobject [-Wmissing-braces] struct dc_surface_update dummy_updates[MAX_SURFACES] = { 0 }; ^ {}

Previous efforts to fix this type of warning by adding or removing braces have been met with some pushback in favor of using memset [1][2]. Do that here, mirroring commit 05794eff1aa6 ("drm/amdgpu/gmc: fix compiler errors [-Werror,-Wmissing-braces] (V2)") in this tree.
