commit 6320e693d98c ("powerpc/perf: Add support for caps
under sysfs in powerpc") added support for caps under sysfs
in powerpc. This added caps directory to:
/sys/bus/event_source/devices/cpu/ for power8, power9, power10
and generic compat PMU in respective PMU driver code.

For power10, it is added under "power10_pmu_attr_groups". But
for DD1 version, attr_groups are defined under dd1 array:
"power10_pmu_attr_groups_dd1". Since caps is not added for DD1,
it fails to include "cpu/caps" in DD1 model. Also issue was
observed while booting power10 pseries with qemu version6,
where as not observed with qemu version7. This could be because
of support for the model in old qemu version. Below is the
trace log:

[...]

Applied to powerpc/next.
