drm/amd/display: Change default policy for MPO with multidisplay 



[Why]
Rearranging pipes with multiple displays and multiple planes cannot be
done atomically and requires a much improved sequence to deal with it.

[How]
To workaround such issues, prefer avoid pipe-split policy for
multidisplay scenarios.
