[media] tuner-core/tda9887: get_afc can be tuner mode specific

The get_afc op in tda9887 is valid only for the radio mode.
But due to the way get_afc in analog_demod_ops was designed it would
overwrite the afc value with a bogus value when in TV mode.
Pass a pointer to the afc value instead, and when not in radio mode
leave it alone in the tda9887.
This broke a long time ago in 2.6.19 when the get_afc op was introduced.
Before that the afc was only set for radio mode in the tda9887.

92002 does.

The difference is that, on model 92001, the tone select is done via
isl6421, while, on other devices, this is done via cx24123 code.
This patch adds a way to override the demod's set_tone at isl6421

only for cx88 Nova S plus model 92001. For all other models and
devices, the set_tone is provided by the demod driver.

Patch originally proposed at bz@9476[1] by Michel Meyers and
John Donoghue but applying the original patch would break support
for all other devices based on isl6421.

Since the FIMC-IS firmware communicates with an image sensor directly

enabled from left to right or disabled from right to left along the
