EDAC/amd64: Add support for family 0x19, models 0x90-9f devices
AMD Models 90h-9fh are APUs. They have built-in HBM3 memory. ECC support
is enabled by default.
APU models have a single Data Fabric (DF) per Package. Each DF is
visible to the OS in the same way as chiplet-based systems like Zen2
CPUs and later. However, the Unified Memory Controllers (UMCs) are
arranged in the same way as GPU-based MI200 devices rather than
CPU-based systems.
Use the existing gpu_ops for hetergeneous systems to support enumeration
of nodes and memory topology with few fixups.
