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.
