[media] bttv: do not switch to the radio tuner unless it is accessed

Just opening the radio tuner should not cause a switch to the radio tuner.
Only after calling g/s_tuner or g/s_frequency should this happen.
This prevents audio being unmuted as soon as the driver is loaded because
some process opens /dev/radioX just to see what sort of node it is, which
switches on the radio tuner and unmutes audio.
This code can be improved further by actually keeping track of who owns the
tuner and returning -EBUSY if switching tuner modes will cause problems.
But for now just fix the annoying case where on boot the radio turns on

[media] em28xx-dvb: Don't put device in suspend mode at feed stop

Putting em28xx in suspend mode when a feed stops is just plain
wrong. Every time a new PES filter is changed, the DVB demux
code will stop the current feed, and then start a new one.
If are there any code that switches off the frontend, via
some GPIO setting, this would make the DVB fail.
This condition was actually trigged with one device, during
DVB scan, as, during scan, it is common that userspace apps
to change the filter several times, in order to get all
tables.
Also, this is not needed at all, since the em28xx code already
hooks into ops.ts_bus_ctrl(). This warrants that em28xx can
check there if DVB frontend is in usage or not. The code there
already puts the device on suspend mode, if the DVB frontend
is not used (closed).

[media] cx231xx: Improve signal reception for PV SBTVD

Instead of using 3.3 MHz IF, use 4MHz. That's the standard
value for the demod, and, while it can be adjusted, 3.3 MHz
is out of the recommended range. So, let's stick with the
default.
With regards to the IF voltage level, instead of using
0.5 V(p-p) for IF, use 2V, giving a 12dB gain.
The rationale is that, on PixelView SBTVD Hybrid,
even 2V(p-p) would be in the nominal range for IF,
as the maximum range on this particular device is 3V.
A higher gain here should help to improve reception under
weak signals.
