We need to clear out the field before setting individual bits, or else we end
up with a union of whatever was there and what we are trying to set. For
example, switching to digital mode ends up being 0x30 instead of 0x10 if we
were previously in analog tv mode.

Move the responsibility for setting up the horizontal and vertical scalers
entirely to the cx25840 driver. The cx231xx-avcore was actually programming
garbage into the HSCALE_CTRL and VSCALE_CTRL registers (because of differences
in how the em28xx driver worked, which the cx231xx driver was derived from).
The net effect is that the scaler now works properly (tested with both PAL
and NTSC under mplayer and tvtime).
This patch also gets rid of cx25840 errors showing up in dmesg which say
"720x480 is not a valid size" (since we now properly setup the size of the
active video area).

There is no need for a switch statement here. Use the contents of the board
profile to dictate the tuner driver and i2c address. Eventually if a board
ever comes around which has a different i2c bus than #1, well that should be a
field in the board profile as well.

The current code was sending one videobuf per field (despite having specified
V4L2_FIELD_SEQ_TB during setup). As a result, application which used the
read() interface would work, except they would sometimes have the fields
reversed (depending on the luck of which field the device was on when the
application started VBI capture). The net effect was that CC decoding would
only work about 50% of the time.
Restructure the VBI code a bit so that works like all the other drivers, such
that both fields are delivered in a single videobuf buffer, which ensures that
they are always received in a predictable order.

Configure the tda18271 to use a smaller transaction size by default, which
works around some sort of i2c bug in the Polaris driver (which needs to be
debugged).
This should be safe for other boards (being in tuner-core means it will be
enabled by default), although testing needs to be done.

This patch, which basically reverts 6d77444ac, fixes an occasional
on-boot or on-capture hang on the XO-1 laptop.
It seems like the cafe hardware is flakier than we thought and that in
some cases, the commands get executed but are never reported as completed
(even if we substantially increase the delays before reading registers).
Reintroduce the 1-second CAFE_SMBUS_TIMEOUT to catch and avoid this
strange hardware bug.

This helps to detect when the driver is using the wrong I2C bus (or have
the i2g gate switch pointing to the wrong place), on devices like cx231xx
that just return 0 on reads to a non-existent i2c device.

Many video drivers implement a fixed set of frame formats and thus face a task
of finding the best match for a user-requested format. Implementing this in a
generic function has also an advantage, that different drivers with similar
supported format sets will select the same format for the user, which improves
consistency across drivers.
