drm/amd/display: Use memset to initialize variable in wait_for_training_aux_rd_interval

Clang warns:

drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dp.c:50:57:
warning: suggest braces around initialization of subobject
[-Wmissing-braces]
        union training_aux_rd_interval training_rd_interval = {0};
                                                               ^
                                                               {}
1 warning generated.

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.
