进行Pstate压力测试过程出现mcelog error报错，显示mcelog不支持海光4号CPU

【问题描述】
HG4号平台整机进行Pstate压力测试过程中，系统messages日志会出现mcelog的报错，显示mcelog对当前海光4号CPU不支持，具体报错如下：

Dec  5 09:13:35 DS2_B mcelog[3099]: mcelog: ERROR: Hygon Processor family 24: mcelog does not support this processor.  Please use the edac_mce_amd module instead.

HG反馈OS某个预装软件mcelog不支持HYGON处理器报出log日志
在方德系统上没看到这个报错

anolis 8 使用的mcelog工具为upstream原版，其中的报错信息在 mcelog.c 470行

else if (!strcmp(vendor,"HygonGenuine")) {
                                Eprintf("ERROR: Hygon Processor family %d: mcelog does not support this processor.  Please use the edac_mce_amd module instead.\n", family);

这里已经识别到是海光cpu，建议按照提示换用edac_mce_amd模块后再尝试
相关内核补丁早已合入anck
