Subject: [PATCH 4/5] KVM: x86: selftests: Allow the PMU event filter test for Hygon

At present, the PMU event filter test is only available for Intel and
AMD architecture conditionally, but it is applicable for Hygon
architecture as well.

Since all known Hygon processors can re-use the test cases, so it isn't
necessary to create a wrapper like other architectures, using the
"host_cpu_is_hygon" variable directly.
