Subject: [PATCH v2 0/2] libperf: evlist: Fix --cpu argument on hybrid platform

Since [1] this isn't strictly required anymore, because the failures
due to opening extended type events on 'any' CPU are now skipped.

However, it does reduce quite a few spurious warnings from all the skips
so I think we should still include it.

Separated into two parts so that the first is backportable and the
second is a cleanup. Also if the first one is backported then it will
fix stable Perfs that might not get [1].

Applies on [1].
