Several media drivers use input_(*) functions so they need to depend on
the INPUT config symbol.

- priv->count were wrong. Should be incremented since the first usage;
- forgot to use list_del() to remove the driver;
- Release memory if an error occurs during _attach

I2C bus redesign changed i2c parameters. This patch re-adds tuner xc2028
attach function, replacing the parameters to the newer syntax.
Signed-off-by: NMauro Carvalho Chehab <mchehab@infradead.org>

The bus-based I2C subsystem allocates the i2c_client struct. So if in order to
be able to convert the tuner to the bus-based I2C API the embedded i2c_client
struct must be removed from the tuner struct and replaced with a pointer.

If the chip isn't recognized, then the correct errors should be returned.
The v4l2_i2c_attach() utility function will return 0 for all errors
except -ENOMEM to provide proper compatibility support for the old I2C

Two new headers were added: one for I2C drivers that are only used
by V4L2 drivers converted to the new bus-based I2C API, and one that
can be used by both converted and unconverted drivers (at the expense of
some additional overhead).

To support the legacy I2C API a helper function was added to v4l2-common.c.

These headers take care of all the 'boilerplate' code that all V4L2 I2C drivers
have in common and will automatically support the bus-based I2C API introduced
in kernel 2.6.22.

In some designs, the tuner silicon may be on an i2c bus behind an i2c gate,
controlled by the analog demodulator.  We already have a method to control
such i2c gates when they are controlled by the digital demodulator, but in
some hybrid designs, there may be an i2c gate controlled by each demodulator.

For example, when in analog tuning mode, one would access the tuner by opening
the i2c gate controlled by the analog demodulator, while when in digital
tuning mode, one would access the tuner by opening the i2c gate controlled by
the digital demodulator.

We must add this callback function to analog_tuner_ops in order to handle
such configurations.
