drm/amdgpu: Fix undue fallthroughs in golden registers initialization

commit 5694785cf09bf0e7bd8e5f62361ea34fa162a4a0 upstream.

As I was staring at the si_init_golden_registers code, I noticed that
the Pitcairn initialization silently falls through the Cape Verde
initialization, and the Oland initialization falls through the Hainan
initialization. However there is no comment stating that this is
intentional, and the radeon driver doesn't have any such fallthrough,
so I suspect this is not supposed to happen.
