From: Sachi King nakato@nakato.io Date: Sat, 2 Oct 2021 14:18:39 +1000 Subject: [PATCH] platform/x86: amd-pmc: Add alternative acpi id for PMC controller

The Surface Laptop 4 AMD has used the AMD0005 to identify this controller instead of using the appropriate ACPI ID AMDI0005. Include AMD0005 in the acpi id list.
