Essentially if a snd_em28xx_capture_trigger() stop followed by a snd_em28xx_capture_trigger() start would not yield any
data because there was some logic put in with an adev->shutdown variable which did not seem warranted in my humble opinion.
It would cause snd_em28xx_capture_trigger start never to start up the audio stream until the device was closed and
reopened again. Upon re-opening the device adev->shutdown is reset and audio data would again flow.

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.

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.

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.
