Subject: [PATCH] powerpc/perf: Fix Power9 test_adder field

Commit 8d911904f3ce4 ('powerpc/perf: Add restrictions to PMC5 in power9 DD1')
was added to restrict the use of PMC5 in Power9 DD1. Intend is to diable
the use of PMC5 using raw event code. Commit instead of updating "power9_isa207_pmu"
structure, updated "power9_pmu" structure. Patch to fix the same.

Fixes: 8d911904f3ce4 ('powerpc/perf: Add restrictions to PMC5 in power9 DD1')
