[igt-dev] [PATCH i-g-t v2 2/3] tests/vc4_perfmon: Make sure vc4 supports perfmon

[Maíra Canal]

Performance Monitors for the vc4 were introduced in Linux 4.17, so a
check if vc4 supports Performance Monitors is essential to assure that
the tests will perform correctly. Therefore, check if vc4 has
perfmon support before running the tests.
