powerpc/perf: Fix Power9 test_adder fields
Commit 8d911904f3ce4 ('powerpc/perf: Add restrictions to PMC5 in power9
DD1')
was added to restrict the use of PMC5 in Power9 DD1. Intention was to
disable
the use of PMC5 using raw event code. But instead of updating the
power9_isa207_pmu structure (used on DD1), the commit incorrectly updated
the
power9_pmu structure. Fix it.

DD1")

Commit 8c218578fc is available with kernel 4.12-rc7 afterwards.
I don't see this fix in the Ubuntu 16.04.3 Zesty tree (the P9 hwe
kernel, 4.10 based).
Need to mirror to Canonical to request they pull in:
