perf/x86/intel: Correct incorrect 'or' operation for PMU capabilities

When running perf-stat command on Intel hybrid platform, perf-stat
reports the following errors:

sudo taskset -c 7 ./perf stat -vvvv -e cpu_atom/instructions/ sleep 1

Opening: cpu/cycles/:HG
------------------------------------------------------------
perf_event_attr:
type 0 (PERF_TYPE_HARDWARE)
config 0xa00000000
disabled 1
------------------------------------------------------------
sys_perf_event_open: pid 0 cpu -1 group_fd -1 flags 0x8
sys_perf_event_open failed, error -16

Performance counter stats for 'sleep 1':

<not counted> cpu_atom/instructions/

It looks the cpu_atom/instructions/ event can't be enabled on atom PMU
even when the process is pinned on atom core. Investigation shows that
exclusive_event_init() helper always returns -EBUSY error in the perf
event creation. That's strange since the atom PMU should not be an
exclusive PMU.

Further investigation shows the issue was introduced by commit:

97588df87b56 ("perf/x86/intel: Add common intel_pmu_init_hybrid()")

The commit originally intents to clear the bit PERF_PMU_CAP_AUX_OUTPUT
from PMU capabilities if intel_cap.pebs_output_pt_available is not set,
but it incorrectly uses 'or' operation and leads to all PMU capabilities
bits are set to 1 except bit PERF_PMU_CAP_AUX_OUTPUT.

Testing this fix on Intel hybrid platforms, the observed issues
disappear.
