powerpc/perf: Properly detect mpc7450 family
Unlike PVR_POWER8, etc ...., PVR_7450 represents a full PVR
value and not a family value.
To avoid confusion, do like E500 family and define the relevant
PVR_VER_xxxx values for the 7450 family:
0x8000 ==> 7450
0x8001 ==> 7455
0x8002 ==> 7447
0x8003 ==> 7447A
0x8004 ==> 7448
And use them to detect 7450 family for perf events.
