drm/amdgpu/swsmu: default to fullscreen 3D profile for dGPUs

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2099996

commit ec1aab7816b06c32f42935e34ce3a3040c778afb upstream.

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.
