perf, x86: Enable not tagged retired instruction counting on P4s
This should turn on instruction counting on P4s, which was missing in
the first version of the new PMU driver.
It's inaccurate for now, we still need dependant event to tag mops
before we can count them precisely. The result is that the number of
instruction may be lifted up.
