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.

Assuming people are fine with this new cap, I like this idea of a lighter privilege for i915-perf.
