[ Upstream commit 292c2116b2ae84c7e799ae340981e60551b18f5e ]
For certain dual display configs that had one display using a 1080p mode, the DPM level used to drive the configs regressed from DPM 0 to DPM 3. This was caused by a missing check that should have only limited the pipe segments on non-phantom pipes. This caused issues with detile buffer allocation, which dissallow subvp from being used
