Clean up use of VIDIOC_G_TUNER; we now correctly gather info from all
the I2C client modules. Also abide by V4L2_TUNER_CAP_LOW
appropriately.

Ensure we don't accidentally broadcast the standard while in radio mode.

This is the logic that supports switching modes via e.g.,
echo radio > /sys/class/pvrusb2/sn-*/ctl_input/cur_val.
To do the mode switching we need to a) broadcast AUDC_SET_RADIO and
b) issue the CX2341X_ENC_MUTE_VIDEO command to the encoder. The first is
done by adding a new pvr2_i2c_op and having it trigger on input change,
the second by adding this command in pvr2_encoder_start() and requesting
an encoder restart on input change by setting stale_subsys_mask appropriately.
The clues about AUDC_SET_RADIO and CX2341X_ENC_MUTE_VIDEO were kindly provided
by Hans Verkuil on the pvrusb2 mailing list. The idea to implement mode
switching this way (on input change) is due to Mike Isely.
Why AUDC_SET_RADIO/VIDIOC_S_STD are used for switching? I can 't be sure, but
I think this can be traced to a cornell student being the first to implement
radio support in ivtv "as a different standard". I think the rest just evolved
from there (it 's in the ivtv ML archives).

Use NULL instead of 0 for pointer value, eliminate sparse warnings.

Support for 24xxx devices was previously explicitly bracketed with
CONFIG_VIDEO_PVRUSB2_24XXX inside the code because we didn't trust the
stability of these changes. We trust it now; so there's no reason to
leave this out of the driver anymore.

Since there are lingering stability problems with support of the newer
PVR USB2 model 24xxx series hardware, I have isolate those changes
with a config option. This commit leaves that option off.

Implement new logic in pvrusb2 to operate wm8775, which is needed for
new model 24xxx hardware which has a wm8775 inside it (which is used
to digitize audio from composite and s-video input).

This adds new logic to integrate the pvrusb2 driver with the V4L
cx25840 module.

The pvrusb2 driver was not correctly identifying and handling the
tda9887 module. This is the bug fix (code had been ifdef'ed out which
should not have been).
