[PATCH 3/4] drm/amdgpu/swsmu: default to fullscreen 3D profile for dGPUs

[Alex Deucher]

This uses more aggressive hueristics than the the bootup default
profile.  On windows the OS has a special fullscreen 3D mode
where this is used.  Since we don't have the equivalent on Linux
default to this profile for dGPUs.
