This reverts commit a6f9761743bf35b052180f4a8bdae4d2cc0465f6.
Remove this commit as it is no longer necessary. The relevant bugs were fixed properly in: drm/radeon/kms: hopefully fix pll issues for real (v3) 5b40ddf888398ce4cccbf3b9d0a18d90149ed7ff drm/radeon/kms: add missing frac fb div flag for dce4+ 9f4283f49f0a96a64c5a45fe56f0f8c942885eef
