The power PMU group constraints includes check for EBB events

But in the existing check, settings for constraint mask and
value is interchanged. Patch fixes the same.

Before the patch, PMU selftest "cpu_event_pinned_vs_ebb_test"
fails with below in dmesg logs. This happens because EBB event
gets enabled along with a non-EBB cpu event.

Applied to powerpc/next.
