perf/x86/intel/uncore: Get UPI NodeID and GroupID

Browse source

The GIDNIDMAP register of UBOX device is used to get the topology
information in the snbep_pci2phy_map_init(). The same approach will be
used to discover UPI topology for ICX and SPR platforms.

Move common code that will be reused in next patches.
