Subject: [PATCH 080/105] drivers/perf: xgene_pmu: Fix IOB SLOW PMU parser
 error

Git-commit: a45fc268db20ecd859bb61e25045912b3194b5e6
Patch-mainline: v4.18-rc3
References: fate#325865,fate#325861

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.
