drm/amdgpu: update ecc query support for arcturus
arcturus and sienna_cichlid share the same version of umc_info interface (umc_info v33). arcturus uses umc_config to indicate ECC capability, while sienna_cichlid uses umc_config1 to indicate ECC capability. driver needs to check either umc_config or umc_config1 to decide ECC capability for ASICs that use umc_info v33 interface.
