Subject: [PATCH iwl-next 2/3] i40e: Add other helpers to check version of running firmware and AQ API

Add another helper functions that will be used by subsequent
patch to refactor existing open-coded checks whether the version
of running firmware and AdminQ API is recent enough to provide
certain capabilities.
