For i2c normal work, we need to slow down the bus speed. However, the
slow down breaks the eeprom firmware load. So, use normal speed for
eeprom booting and then restore the i2c speed after that.
It should also be noticed that no other I2C transfer should be in course
while booting from eeprom, otherwise, tda10046 goes into an instable
state. So, proper locking are needed at the i2c bus master.
Tested with saa7134 MSI TV @nyware A/D board, that comes with an eeprom
with firmware version 29.

KBL is not needed on saa7134, so, let's remove it.
However, we should take some care to avoid opening the module while
initializing it. This issue exists with newer udev's that opens a device
as soon as the driver is registered. So, a proper lock is needed on
open.

Fix two broken controls where a step weren't specified. Without a step,

Some saa7134 devices require to open an i2c gate before tuning. This
patch fix the initialization for those devices.
The nxt200x_gate_ctrl() logic were returned back to the old place, since
we don't know how to close the gate. A future pacth could revert that
change and provide the proper close gate control, to avoid keeping it
open forever.

On certain devices, before opening a tuner, we need to open the tuner
gate via i2c.
This patch just moves the tuner probing code to the same place where
such i2c commands are handled, to make easier to fix this trouble on
later patches.

While here, be sure that gate will be kept disabled if an error occurs.

The gate control logic is broken: several routines just keep it open;
other rotines close it properly; there are even other routines that
assumes that it is open without really checking or opening it.
Instead of having to manually handle the gate control and having such
troubles, let a sub-routine take care of the gate, opening it before
i2c_transfer and closing it after that. This avoids leaving the gate
into a random state.

Doing the v4l2_device registration in the saa7146 core will make it

Modified mxb to load the i2c modules through v4l2_subdev. So no more probing.
Modified tea6415c and tea6420 to use the standard routing ops to do the
routing, rather than using private commands. Dropped the private commands
from tda9840 (they were never used except during initialization of the
module).
Added saa7146 support for VIDIOC_DBG_G_CHIP_IDENT.
Converted saa5246a and saa5249 to v4l2_subdev.

Sliced VBI, in the manner that ivtv implements it as a separate data stream,
now works for 525 line 60 Hz systems like NTSC-M. It may work for 625 line
50 Hz systems, but I have more engineering work to do, to verify it is operating
properly. Sliced data insertion into the MPEG PS should be working, but is
untested.

The cx23418 appears to send Raw VBI buffers with a PTS on a per frame
basis, not per field, so process Raw VBI on a whole frame basis and reduce
some complexity. Fix VBI buffer size computation to handle a whole
frame of Raw VBI for a 625 line system, which is the worst case and will
work for 525 lines systems as well.

Fixed an endianess problem with the collection of the PTS from

last 12 bytes of the last line of each field, to remove artifacts
created by removing the first 12 bytes of each field for raw VBI.

The Encoder will only allow the Raw VBI parameters, along with a number of
other API parameters, to take effect when no analog captures are in
progress. These parameters must be set before the first analog capture starts,
be it MPEG, VBI, YUV, etc., and cannot be changed until the last one stops. It
is not obvious to me what capture channel API parameters are shared and which
ones must be set per capture channel, so set them all for every analog
capture channel start up. This fixes the driver so that VBI capture can be
started up after the MPEG capture is going.

The old code from ivtv used a CX23415/6 PTS, which was simply left at 0 in the
cx18 driver. Since the CX23418 gives us what I think is a PTS (or some other
90 kHz clock count) with each VBI buffer, this change has the cx18 driver use
that as a PTS.
