[PATCH 24/28] drm/amd/display: do not skip ODM minimal transition based on new state

[Stylon Wang]

From: Wenjing Liu <wenjing....@amd.com>

[why]
During 8k video plane resizing we could transition from MPC combine mode
back to ODM combine 2:1 + 8k video plane. In this transition minimal
transition state is based on new state with ODM combine enabled.
We are skipping this and it causes corruption because we have to reassign
a current DPP pipe to a different MPC blending tree which is not supported
seamlessly.
