perf/x86/intel/uncore: Enable UPI topology discovery for Skylake Server
UPI topology discovery relies on data from KTILP0 (offset 0x94) and
KTIPCSTS (offset 0x120) registers which reside under IIO bus(3) on
SKX/CLX.
This patch enable UPI topology discovery on Skylake Server. Topology is
exposed through attributes /sys/devices/uncore_upi_<pmu_idx>/dieX,
where dieX is file which holds "upi_<idx1>:die_<idx2>" connected to
this UPI link.
