Subject: [PATCH AUTOSEL 6.12 30/36] ACPI/IORT: Add PMCG platform information for HiSilicon HIP09A

From: Qinxin Xia <xiaqinxin@...wei.com>

[ Upstream commit c2b46ae022704a2d845e59461fa24431ad627022 ]

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.
