Those callbacks are meant to be used only on some very specific cases. There's absolutely no need to do that at tda8261, as the only parameter that it allows to be set/get is the frequency. So, use the standard get_params() and get_frequency() kABI ops. There's no need to touch at any bridge driver, as all interactions are done via the macros at tda8261_cfg.h.
