Upcoming I2C v4l2_subdev drivers need a way to control the subdevice
power state from the core. This use case is already partially covered by
the tuner s_standby operation, but no way to explicitly come back from
the standby state is available.
Rename the tuner s_standby operation to core s_power, and fix tuner
drivers accordingly. The tuner core will call s_power(0) instead of
s_standby(). No explicit call to s_power(1) is required for tuners as
they are supposed to wake up from standby automatically.

for v4l2_device
Add v4l2_subdev_ir_ops and IR notify defines for v4l2_device. This change
is specifically needed at this time to support the integrated IR controller in
the CX2388[58] chips.

v4l2_i2c_new_subdev_cfg/board calls
Add a new s_config core ops call: this is called with the irq and platform
data to be used to initialize the subdev.
Added new v4l2_i2c_new_subdev_cfg and v4l2_i2c_new_subdev_board calls
that allows you to pass these new arguments.
The existing v4l2_i2c_new_subdev functions were modified to also call
s_config.
In the future the existing v4l2_i2c_new_subdev functions will be replaced
by a single v4l2_i2c_new_subdev function similar to v4l2_i2c_new_subdev_cfg
but without the irq and platform_data arguments.

v4l2_device.
Until now I relied on i2c_del_adapter to unregister the i2c_clients for
me, however, if the i2c bus is a platform bus then it is never deleted.
So instead I need to unregister i2c clients when unregistering the
v4l2_device.

It is no longer needed to use a struct pointer as argument, since v4l2_subdev
doesn't require that ioctl-like approach anymore. Instead just pass the input,
output and config (new!) arguments directly.

v4l2_subdev.
With all the v4l2_subdev changes that were made to these drivers it is a
good idea to increase the version number of each driver.
It's just the patch level that is increased, except for the zoran and saa7146
drivers where the minor number was increased due to the more substantial
changes that were made to those two drivers.

s_std didn't belong in the tuner ops. Stricly speaking it should be part of
the video ops, but it is used by audio and tuner devices as well, so it is
more efficient to make it part of the core ops.

core->init.
The init callback was used in several places to load firmware. Make a separate
load_fw callback for that. This makes the code a lot more understandable.

Now that all drivers are converted to v4l2_subdev we can remove legacy code
in v4l2-common. Also move the documentation of the internal API to
v4l2-subdev.h where it really belongs.

Remain consistent in the naming: fields pointing to v4l2_device should
be called v4l2_dev. There are too many device-like entities without
adding to the confusion by mixing naming conventions.

instead of ID.
Since the i2c driver ID will be removed in the near future we have to
modify the v4l2 debugging API to use the driver name instead of driver ID.
Note that this API is not used in applications other than v4l2-dbg.cpp
as it is for debugging and testing only.
Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged
with a warning that it is deprecated and will be removed in 2.6.30.

Since internal to v4l2 the ioctl prototype is the same regardless of it
being called through .ioctl or .unlocked_ioctl, we need to convert it all
to the long return type of unlocked_ioctl.
Thanks to Jean-Francois Moine for posting an initial patch for this and
thus bringing it to our attention.
