netlink: specs: Expand the pse netlink command with PoE interface

Add the PoE pse attributes prefix to be able to use PoE interface.

Example usage:
./ynl/cli.py --spec netlink/specs/ethtool.yaml --no-schema --do pse-get \
             --json '{"header":{"dev-name":"eth0"}}'
{'header': {'dev-index': 4, 'dev-name': 'eth0'},
 'c33-pse-admin-state': 3,
 'c33-pse-pw-d-status': 4}

./ynl/cli.py --spec netlink/specs/ethtool.yaml --no-schema --do pse-set \
             --json '{"header":{"dev-name":"eth0"},
		     "c33-pse-admin-control":3}'
