drm/amdgpu: only harvest gcea/mmea error status in arcturus
SDP RdRspStatus/WrRspStatus or first parity error on
RdRsp data can cause system fatal error in arcturus.
GPU will be freezed in such case.
Driver needs to harvest these error information before
reset the GPU. Check error type to avoid harvest normal
gcea/mmea information.
