perf/x86/intel: Fix event constraints for ICL
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.
