EDAC/i10nm: Add Intel Granite Rapids-D support
The Granite Rapids-D CPU model uses memory controller registers similar
to those of the Granite Rapids server CPU but with a different memory
controller MMIO base.
Add the Granite Rapids-D CPU model ID and use the new memory controller
MMIO base for EDAC support.
