EDAC/skx_common: Prepare for skx_get_edac_list() 

The Intel EDAC library 'skx_common' maintains the Intel server EDAC device
list for {skx, i10nm}_edac drivers, which use skx_get_all_bus_mappings()
to build and retrieve the EDAC device list.

However, the upcoming Intel EDAC driver, imh_edac, for Diamond Rapids
servers is designed for memory controllers that are MMIO-based devices
rather than PCI devices. Consequently, it can't use
skx_get_all_bus_mappings() due to the absence of a PCI bus. To accommodate
this, prepare skx_get_edac_list() to enable the upcoming imh_edac driver
to obtain the EDAC device list from the skx_common library and build the
EDAC device list independently.
