EDAC/igen6: Add several Intel Raptor Lake-P SoCs support

Mainline: commit d23627a("EDAC/igen6: Add Intel Raptor Lake-P SoCs support")
from: v6.8-rc1

Add several Intel Raptor Lake-P SoC compute die IDs for EDAC support.
These Raptor Lake-P SoCs use similar memory controller and IBECC as
Alder Lake-P SoC but extend the most significant bit of error address
logged in IBECC from bit 38 to bit 45.
