[PATCH] perf: xgene: Fix IOB SLOW PMU parser error

[hoan.tran@amperecomputing.com (Hoan Tran)]

This patch fixes the below parser error of the IOB SLOW PMU.

        # perf stat -a -e iob-slow0/cycle-count/ sleep 1
        evenf syntax error: 'iob-slow0/cycle-count/'
                                 \___ parser error

It replaces the "-" character by "_" character inside the PMU name.
