2020-08-03selftests/powerpc: Skip vmx/vsx/tar/etc tests on older CPUsMichael Ellerman1-0/+3
Some of our tests use VSX or newer VMX instructions, so need to be skipped on older CPUs to avoid SIGILL'ing. Similarly TAR was added in v2.07, and the PMU event used in the stcx fail test only works on Power8 or later.
