From: Andi Kleen <ak@linux.intel.com>
[ Upstream commit 6bdfd9f118bd59cf0f85d3bf4b72b586adea17c1 ]
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.
