[PATCH] KVM: selftest: Add family and model check for zen4 in PMU filter test

[Manali Shukla <manali.shukla@xxxxxxx>]

PMU event filter test fails on zen4 architecture because of
unavailability of family and model check for zen4 in use_amd_pmu().
So, add family and model check for zen4 architecture in use_amd_pmu().
