drm/amdgpu: enable freesync for A+A configs

Browse Source 
Some newer APUs can scanout directly from GTT, that saves us from
allocating another bounce buffer in VRAM and enables freesync in such
configurations.

Without this patch creating a framebuffer from the imported BO will
fail and userspace will fall back to a copy.
