The discovery table of UPI on some SPR variants, e.g., MCC, is broken. The third UPI table may includes a wrong address which points to a non-exists device. The bug impacts both UPI and M3UPI uncore PMON. Use a pre-defined UPI and M3UPI table to replace the broken table. Different BIOS may populate a device into a different domain or a different BUS. The accurate location can only be retrieved at load time. Add spr_update_device_location() to update the location of the UPI and M3UPI in the pre-defined table.
