nfp: flower: add per repr private data for LAG offload

Browse Source 
Add a bitmap to each flower repr to track its state if it is enslaved by a
bond. This LAG state may be different to the port state - for example, the
port may be up but LAG state may be down due to the selection in an
active/backup bond.
