I using amd 3400g running with android-x86, this patch is a bad commit when i use android-x86 on amdgpu.

Revert "Revert "drm/amdgpu: Ensure that the modifier requested is supported by plane."" is the first bad commit, cause a androidx86 run on amdgpu problem, look the video, https://drive.google.com/file/d/1QklH_H2AlOTu8W1D3yl6_3rtZ7IqbjR_/view?usp=sharing
