Revert "drm/msm/dpu: support plane splitting in quad-pipe case"
This reverts commit 5978864e34b66bdae4d7613834c03dd5d0a0c891.
At least on Hamoa based devices, there are IOMMU faults:
arm-smmu 15000000.iommu: Unhandled context fault: fsr=0x402, iova=0x00000000, fsynr=0x3d0023, cbfrsynra=0x1c00, cb=13
arm-smmu 15000000.iommu: FSR = 00000402 [Format=2 TF], SID=0x1c00
arm-smmu 15000000.iommu: FSYNR0 = 003d0023 [S1CBNDX=61 PNU PLVL=3]
While on some of these devices, there are also all sorts of artifacts on eDP.
Reverting this fixes these issues.
