[Intel-gfx] [RFC 0/2] Support perf stat with i915 PMU

[Dmitry Rogozhkin]

These patches depend on the RFC patches enabling i915 PMU from Tvrtko:
  https://patchwork.freedesktop.org/series/27488/
Thus, CI failure to build them is expected. I think that my patches should
be squeashed in Tvrtko's one actually.

The first patch simply reorders functions and does nothing now comparing to
Tvrtko's patches. Next patches adds fixes according to PMU API comments
and clarifications from PMU aware engineers.
