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.
