Rob Herring 87d95ff0ca arm_pmu: Validate single/group leader events
commit e5c23779f9 upstream.

In the case where there is only a cycle counter available (i.e.
PMCR_EL0.N is 0) and an event other than CPU cycles is opened, the open
should fail as the event can never possibly be scheduled. However, the
event validation when an event is opened is skipped when the group
leader is opened. Fix this by always validating the group leader events.
