KVM: selftests: Treat AMD Family 17h+ as supporting branch insns retired
When detecting AMD PMU support for encoding "branch instructions retired"
as event 0xc2,0, simply check for Family 17h+ as all Zen CPUs support said
encoding, and AMD will maintain the encoding for backwards compatibility
on future CPUs.
Note, the kernel proper also interprets Family 17h+ as Zen (see the sole
caller of init_amd_zen_common()).
