Revert "Revert "drm/amdgpu/display: change pipe policy for DCN 2.0"" 

This reverts commit 27dd79c0.

It appears MPC_SPLIT_DYNAMIC still causes problems with multiple
displays on DCN2.0 hardware.  Switch back to MPC_SPLIT_AVOID_MULT_DISP.
This increases power usage with multiple displays, but avoids hangs.
