nfp: flower: offload list of IPv6 tunnel endpoint addresses
Fw requires a list of IPv6 addresses that are used as tunnel endpoints to
enable correct decap of tunneled packets.
Store a list of IPv6 endpoints used in rules with a ref counter to track
how many times it is in use. Offload the entire list any time a new IPv6
address is added or when an address is removed (ref count is 0).
