!12216 ACPI/IORT: Add PMCG platform information for HiSilicon HIP10/11

Merge Pull Request from: @zhangqizhi3 
 
HiSilicon HIP10/11 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.
