[PATCH v2] ACPI/IORT: Add PMCG platform information for HiSilicon HIP09A

[Qinxin Xia]

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.

Update the silicon-errata.rst as well.
