[media] em28xx: improve em2710/em2820 distinction

Chip id 18 is used by the em2710 and em2820.
The current code assumes that if the device is a camera, the chip is an em2710
and an em2820 otherwise.
But it turned out that the em2820 is also used in camera devices.
"Silvercrest 1.3 MPix" webcams for example are available with both chips.
Fortunately both variants are using different generic USD IDs which give us a
hint about the used chip.

The get_rf_strength op in tuner-simple is valid only for the radio mode.
But due to the way get_signal in analog_demod_ops was designed it would

Pass a pointer to the signal value instead, and when not in radio mode
leave it alone in the tuner-simple.
This broke in commit 030755bde42bbed133182b0ece7c7a9c759478e8
(tuner-core: call has_signal for both TV and radio) in kernel 3.6. Before

[media] cx88: kernel bz#9476: Fix tone setting for Nova-S+ model 92001

Hauppauge Nova-S-Plus DVB-S model 92001 does not lock on horizontal
polarisation. According with the info provided at the BZ, model
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
driver. In order to avoid regressions, the override is enabled
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.
