Reverting this patch restores the GPU to functionality:

As nearly all POWER distros ship a 64k page kernel, the switch from AMDGPU_GPU_PAGE_MASK to PAGE_MASK may be at fault.
As an aside, it seems there is little to no QA for POWER desktop systems from the Debian developers. If this is due to lack of hardware access, we may be able to assist.
