octeontx2-af: Add new devlink param to configure maximum usable NIX block LFs
On some silicon variants the number of available CAM entries are
less. Reserving one entry for each NIX-LF for default DMAC based pkt
forwarding rules will reduce the number of available CAM entries
further. Hence add configurability via devlink to set maximum number of
NIX-LFs needed which inturn frees up some CAM entries.
