Adrian Hunter a25a403e4b perf intel-pt: Fix CYC timestamps after standalone CBR ...

commit 430635a0ef upstream.

After a standalone CBR (not associated with TSC), update the cycles
reference timestamp and reset the cycle count, so that CYC timestamps
are calculated relative to that point with the new frequency.

Fixes: cc33618619 ("perf tools: Add Intel PT support for decoding CYC packets")
