All radio tuners in cx23885 driver using same address for radio and
tuner, so there is no need to probe it twice for same tuner and we can
use radio_type UNSET.
Be aware radio support in cx23885 is not yet committed, so this is only
minor fix for future support.

Added three new control calls (g_std, querystd and g_ctrl) to
the -417 driver. Also routed other controls through the main
cx23885 driver meaning that the controls for the 417 and the
raw video device all enter the driver code and are handled
in a single place.

First in a series of patches that adds support to the cx23885 driver
for CX23888 analog video handling. Raw and MPEG video support is
being added for the HVR1850 driver in the patch, and the following
series of patches.
Some basic cx23885 driver cleanup. Partly to add HVR1850 support
and partly to allow -417.c V4L2 calls to be routed through thr
driver core and handled in a single place.
Make a number of core driver functions available to the -417.c
driver to streamline the driver.
Add the analog tuner ops definition so we can reach/tune the
hardware when we need to. Added the tff field so 888 based cards
(which have a weird field ordering issue) can be accomodated
and worked around in the driver.

Found an odd bug while implementing support for the HVR1850 that
lead to jerky video during the first capture, if the encoder was
not initialized early. I've modied the driver to configure the
encoder early, and this avoids the issue - a reasonable workaround.
Regression tested against the HVR1800 and soon to be added HVR1850

Since the conversion to subdev in Oct 2010 the audio controls have
not functioned correctly in the cx23885 driver. Passing values of
0-3f did not translate into meaningfull register writes. I've
converted the cx23885 driver to match the cx25840 volume control
definition and now audio is working reliably again.

The cx23885-dvb driver has a dirty hack:
1) it hooks the DVBv3 legacy call to FE_SET_FRONTEND;
2) it uses internally the DVBv3 struct to decide some
configs.
Replace it by a change during the gate control. This will
likely work, but requires testing. Anyway, the current way
will break, as soon as we stop copying data for DVBv3 for
pure DVBv5 calls.
Compile-tested only.

There's one comment that has been copied from bttv to many other
media/video drivers:
/* init + register i2c algo-bit adapter */
Meanwhile, many drivers use hardware I2C implementations instead of
relying on i2c-algo-bit, so this comment is misleading. Remove the
reference to "algo-bit" from all drivers, to avoid any confusion. This
is the best way to ensure that the comments won't go out of sync
again. Anyone interested in the implementation details would rather
look at the code itself.

Previous driver over-reported errors and stopped the video fifo
(causing video to stop) if 1) A risc error occured 2) The risc processor
detected that it has missing lines in the video frame 3) The risc fifo
is about to overflow.
The previous driver reported all three of these cases as risc errors
when this is technically not correct. So, the function was cleaned up.
1. Ensure that risc opcode related errors are correctly shown as such,
and not overly reported for non-risc-opcode cases.
2. Ensure that line sync and overflow errors are not reported as opcode errors.
3. Ensure that only the risc-op-code case can stop the fifo and dump channel
/ risc processor information.
The net result is that if video becomes unstable, cable disconnect, this will
not trigger a stop of the video firmware (due to missing lines errors).

1. Removed the verbose 'dump channel state to console', very noisy in
weak signal conditions.
2. No need for the video buffer timeout to stop the risc engine here.
Clearer and easier to maintain if start_video_dma() is the single
place that this is done.

vidioc_g_tuner should not do any memset for the parameters. Core
already does that. In particular, V4L2 core now does some handling
for the tuner type, and the tuner-core module relies on that.
So, doing any memset there is a very bad idea.
