[PATCH 2/2] drm/amdgpu: Add Aldebaran virtualization support

[Zhigang Luo]

1. add Aldebaran in virtualization detection list.
2. disable Aldebaran virtual display support as there is no GFX
   engine in Aldebaran.
3. skip TMR loading if Aldebaran is in virtualizatin mode as it
   shares the one host loaded.
