Subject: [RFC PATCH v1] ice: add CGU info to devlink info callback
If Clock Generation Unit and dplls are present on NIC board user shall
know its details.
Provide the devlink info callback with a new:
- fixed type object `cgu.id` - hardware variant of onboard CGU
- running type object `fw.cgu` - CGU firmware version
- running type object `fw.cgu.build` - CGU configuration build version
These information shall be known for debugging purposes.
Test (on NIC board with CGU)
$ devlink dev info <bus_name>/<dev_name> | grep cgu
cgu.id 8032
fw.cgu 6021
fw.cgu.build 0x1030001
Test (on NIC board without CGU)
$ devlink dev info <bus_name>/<dev_name> | grep cgu -c
0
