EDAC/igen6: Add Intel Wildcat Lake SoCs support 



Intel Wildcat Lake is a mobile derivative of Panther Lake with one
memory controller. Wildcat Lake SoCs share the same IBECC registers
with Meteor Lake-P SoCs.

Add a compute die ID and a new configuration structure for Wildcat
Lake SoCs with In-Band ECC capability for EDAC support.
