powerpc/perf: Include caps feature for power10 DD1 version

Commit d1587f82640e ("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.

The issue was observed while booting power10 pseries with qemu version
6, but not observed with qemu version 7. This is because qemu version 7
uses a DD 2.0 CPU model.

Below is the trace log:

Fix it by adding caps for dd1 attr_groups in power10 PMU driver.
