drm/amd/display: Set MPC_SPLIT_DYNAMIC for DCN301
Since DC version 3.2.226, DC started to use a new internal commit
sequence that better deals with hardware limitations. Usually, DC adopts
split pipe dynamics to improve the display bandwidth and, in some cases,
to save power. This commit sets MPC_SPLIT_DYNAMIC for DCN301, improving
the bandwidth and fixing the cursor bug on KDE when it tries hardware
rotation.
