drm/amd/display: Disable MPC split by default on special asic
[WHY]
All of pipes will be used when the MPC split enable on the dcn
which just has 2 pipes. Then MPO enter will trigger the minimal
transition which need programe dcn from 2 pipes MPC split to 2
pipes MPO. This action will cause lag if happen frequently.
[HOW]
Disable the MPC split for the platform which dcn resource is limited
