perf/x86/intel/uncore: Fix PCI BDF address of M3UPI on SKX

The counters on M3UPI Link 0 and Link 3 don't count properly, and writing
0 to these counters may causes system crash on some machines.

The PCI BDF addresses of the M3UPI in the current code are incorrect.

The correct addresses should be:

  D18:F1 0x204D
  D18:F2 0x204E
  D18:F5 0x204D
