EDAC/ie31200: Add Intel Raptor Lake-S SoCs support

The Intel Raptor Lake-S SoC contains two memory controllers with DDR5
memory type and out-of-band ECC capability. The resource definitions of
the memory controller are different from previous generations. One notable
difference is that the PCI ERRSTS register is deprecated and is not used
to indicate the presence of errors or to clear the MMIO-mapped ECC error
log regsiters.

Extend the ie31200_edac driver to support multiple memory controllers,
add a resource configuration table and use an MSR register to clear the
ECC error log registers to provide EDAC support for Raptor Lake-S SoCs.
