Abel Vesa 35ab5123bd Revert "drm/msm/dpu: support plane splitting in quad-pipe case" ...

This reverts commit 5978864e34.

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.
