devlink: generate the port function policy from the spec

Browse source

devlink has a one huge root attribute set for the whole family,
we haven't taken the time to properly define the sub-sets for
each command. Do it for port-set so that we can drop the hand
written policy used by devlink_port_function_set().

We need this subsetting because within the DEVLINK_ATTR_PORT_FUNCTION
nest DEVLINK_PORT_FN_ATTR_OPSTATE and DEVLINK_PORT_FN_ATTR_DEVLINK
are output-only so we have to filter them out of the input set.
