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
