drm/amdgpu: add EDC support for CZ (v3)
This adds EDC support for CZ. EDC = Error Correction and Detection This code properly initializes the EDC hardware and resets the error counts. This is done in late_init since it requires the IB pool which is not initialized during hw_init. v2: fix the IB size as noted by Felix, fix shader pgm register programming v3: use the IB for the shaders as suggested by Christian Reviewed-by: Christian K├Ânig <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
