[PATCH 5.4 006/411] perf/x86/intel: Fix event constraints for ICL

[Greg Kroah-Hartman]

From: Kan Liang <kan.liang@xxxxxxxxxxxxxxx>

commit 86dca369075b3e310c3c0adb0f81e513c562b5e4 upstream.

According to the latest event list, the event encoding 0x55
INST_DECODED.DECODERS and 0x56 UOPS_DECODED.DEC0 are only available on
the first 4 counters. Add them into the event constraints table.
