Revert "drm/amd/display: Only use ODM2:1 policy for high pixel rate displays"
This reverts commit 047783cdd5f604d87398236beb4971abb4d43293 since it
causes higher power consumption for single display use case (4k60).
Also, this patch introduced a 35% performance drop in a Vulkan benchmark.
* The patch disabled the ODM-combination on most popular monitors, including 4K, 2K and FHD monitors at 60Hz.
* ODM-combination can halve the DPP clock to save power, that is the reason why we introduce ODM-combination, and the PM log shows single pipe consumes more power at 4K@60Hz.
* ODM-combination has 2 de-tiled buffer involved, which provides longer self-sustained time, that benefit to the memory power optimization.
