Subject: [PATCH 1/1] EDAC/ie31200: Add two Intel SoCs for EDAC support

Add two compute die IDs for Raptor Lake-S and Alder Lake-S for EDAC
support. Note that because Alder Lake-S shares the same memory controller
registers as Raptor Lake-S, it can reuse the configuration data of Raptor
Lake-S for EDAC support.
