drm/amdgpu: Use DC by default on CIK APUs
Now that DC supports external DP bridge encoders,
it has reached feature parity with the legacy non-DC display
driver on CIK APUs: Kaveri, Kabini, Mullins.
Use the DC display driver by default on SI APUs, unless it is
explicitly disabled using the amdgpu.dc=0 module parameter.
DC brings proper support for DP/HDMI audio, DP MST, VRR,
10-bit colors, some HDR features, atomic modesetting, etc.
