Subject: [PATCH 5.4 33/56] perf/x86/intel: Update event constraints for ICX

From: Kan Liang <kan.liang@...ux.intel.com>

[ Upstream commit ecc2123e09f9e71ddc6c53d71e283b8ada685fe2 ]

According to the latest event list, the event encoding 0xEF is only
available on the first 4 counters. Add it into the event constraints
table.
