!14121 [PATCH OLK-5.10] perf: Add PMCG platform information for HiSilicon HIP09A

Merge Pull Request from: @zhangqizhi3 
 
Description: HiSilicon HIP09A platforms using the same SMMU PMCG with HIP09
and thus suffers the same erratum. List them in the PMCG platform
information list without introducing a new SMMU PMCG Model.
