drm/amd/display: Correct MPC split policy for DCN301
[ Upstream commit ac46d93235074a6c5d280d35771c23fd8620e7d9 ]
[Why]
DCN301 has seamless boot enabled. With MPC split enabled
at the same time, system will hang.
[How]
Revert MPC split policy back to "MPC_SPLIT_AVOID". Since we have
ODM combine enabled on DCN301, pipe split is not necessary here.
