Add dpll device level feature: phase offset monitor.
Phase offset measurement is typically performed against the current active
source. However, some DPLL (Digital Phase-Locked Loop) devices may offer
the capability to monitor phase offsets across all available inputs.
The attribute and current feature state shall be included in the response
message of the ``DPLL_CMD_DEVICE_GET`` command for supported DPLL devices.
In such cases, users can also control the feature using the
``DPLL_CMD_DEVICE_SET`` command by setting the ``enum dpll_feature_state``
values for the attribute.
Implement feature support in ice driver for dpll-enabled devices.
Verify capability:
$ ./tools/net/ynl/pyynl/cli.py \
--spec Documentation/netlink/specs/dpll.yaml \
--dump device-get
[{'clock-id': 4658613174691613800,
'id': 0,
'lock-status': 'locked-ho-acq',
'mode': 'automatic',
'mode-supported': ['automatic'],

{'clock-id': 4658613174691613800,

'lock-status': 'locked-ho-acq',
'mode': 'automatic',

'module-name': 'ice',
'phase-offset-monitor': 'disable',

Enable the feature:
$ ./tools/net/ynl/pyynl/cli.py \
--spec Documentation/netlink/specs/dpll.yaml \
--do device-set --json '{"id":1, "phase-offset-monitor":"enable"}'
Verify feature is enabled:
$ ./tools/net/ynl/pyynl/cli.py \
--spec Documentation/netlink/specs/dpll.yaml \
--dump device-get
