perf/x86/intel/uncore: Enable UPI topology discovery for Icelake Server



UPI topology discovery relies on data from KTILP0 (offset 0x94) and
KTIPCSTS (offset 0x120) as well as on SKX but on Icelake Server these
registers reside under UBOX (Device ID 0x3450) bus.

This patch enables /sys/devices/uncore_upi_*/die* attributes on Icelake
Server.
