Open access to i915_perf monitoring for CAP_SYS_PERFMON privileged processes. For backward compatibility reasons access to i915_perf subsystem remains open for CAP_SYS_ADMIN privileged processes but CAP_SYS_ADMIN usage for secure i915_perf monitoring is discouraged with respect to CAP_SYS_PERFMON capability.
