Subject: [PATCH 2/3] perf jevents: Fix period for Intel fixed counters

From: Andi Kleen <ak@...ux.intel.com>

The Intel fixed counters use a special table to override the JSON
information. During this override the period information from
the JSON file got dropped, which results in inst_retired.any
and similar running with frequency mode instead of a period.
Just specify the expected period in the table.
