There were several issues in the past, caused by the hybrid tuner design, since
now, the same tuner can be used by drivers/media/dvb and drivers/media/video.
Kconfig items were rearranged, to split V4L/DVB core from their drivers.

We currently do not have a method to enable instance staring if i2c adapter
is NULL, in the cases of dvb demods that write to the tuner directly using
calc_regs. Prevent possible wrong instance sharing for these cases until
a better solution can be found.

i2c adapters
Some dvb demodulators access the tuner directly without using i2c.
In these cases, i2c_adap may be NULL. This patch fixes
hybrid_tuner_request_state to allow for NULL i2c_adapters.

hybrid_tuner_release_state
Assign the number of instances remaining as the return value of
hybrid_tuner_release_state, in case there is any extra cleanup that
the tuner driver needs to do after an instance has been destroyed.

instances
Create a macro implementing a standard method to share state amongst
multiple instances of a hybrid tuner object.
Also, prepare tuner_foo printk macros for the removal of PREFIX

- remove dependency of tda8290 module on struct tuner
- move tuner_foo printk macros from tuner-driver.h into tuner-core.c
- clean up #includes of tuner-i2c.h / tuner-driver.h

Issuing register reads as a separate address write and data read transactions
means that other I2C activity could occur in between and state could get out
of sync. Issue both the write and read in a single transaction so that the
i2c layer can prevent other users accessing the bus until we are complete.

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).

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.
