drm/amd: Don't try to enable secure display TA multiple times
If the securedisplay TA failed to load the first time, it's unlikely to work again after a suspend/resume cycle or reset cycle and it appears to be causing problems in futher attempts. Fixes: e42dfa66d592 ("drm/amdgpu: Add secure display TA load for Renoir") Reported-by: Filip Hejsek <filip.hejsek@gmail.com> Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/2633 Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> Acked-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
