selftest/powerpc: Wrong PMC initialized in pmc56_overflow test
Test uses PMC2 to count the event. But PMC1 is being initialized. Patch to fix it. Fixes: 3752e453f6ba ('selftests/powerpc: Add tests of PMU EBBs') Signed-off-by: Madhavan Srinivasan <maddy@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
