Tuan Phan e5154bf217 perf/arm-cmn: Fix invalid pointer when access dtc object sharing the same IRQ number 
[ Upstream commit 4e16f283edc289820e9b2d6f617ed8e514ee8396 ]

When multiple dtcs share the same IRQ number, the irq_friend which
used to refer to dtc object gets calculated incorrect which leads
to invalid pointer.

Fixes: 0ba64770a2 ("perf: Add Arm CMN-600 PMU driver")
