Adds a flower based TC offload handler for representor devices, this
is in addition to the bpf based offload handler. The changes in this
patch will be used in a follow-up patch to add tc flower offload to
the NFP.

The flower app enables tc offloads on representors by default.

Thanks, two nits, since it seems like there will have to be another
