[ Upstream commit c60819149b637d0f9f7f66e110d2a0d90a3993ea ]
In a future change we will need to make ocelot_port_update_active_preemptible_tcs() call vsc9959_tas_guard_bands_update(), but that is currently not possible, since the ocelot switch lib does not have access to functions private to the DSA wrapper.
Move the pointer to vsc9959_tas_guard_bands_update() from felix->info (which is private to the DSA driver) to ocelot->ops (which is also visible to the ocelot switch lib).
