We can tell whether we are tuning television or radio by testing for
struct analog_parameters *params->mode == V4L2_TUNER_RADIO

There is no longer any need for separate set_tv_freq and
set_radio_freq functions in the analog tuner demodulator modules.

Some tuners, like xc3028, need to print error messages. Instead of declaring
local macros, create a tuner global macro for printing tuner errors.

To preserve CodingStyle on all tuner_macros, a few CodingStyle violations were
fixed at the other macros:
	- lines with more than 80 columns
	- two statements at the same line

The patch also removes the CodingStyle violation of having emacs declarations
inside de source code (CodingStyle chapter 18).

The default_mode_mask global is replaced by a list of tuner structs. The
tuner driver now walks that list to see which radio and/or tv tuner
devices are registered to a given i2c adapter.

The default_mode_mask global had to go since this is no longer supported
with the new bus-based I2C API.

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.

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.

To ease the conversion of the analog tuner sub-drivers into dvb_frontend
style tuner modules, we must remove the i2c_client interface.

dvb_frontend style tuner modules use i2c_transfer directly on the i2c_adapter.

This change only alters the interface between tuner.ko and the tuner
sub-drivers. The v4l2 / i2c_client interface to tuner.ko remains intact.

This patch adds inline functions tuner_i2c_xfer_send, and tuner_i2c_xfer_recv,
to replace i2c_master_send and i2c_master_recv inside the tuner sub-drivers.
