tuner-core.c contains a hack for cx88 board to prevent probing of certain
addresses:
/* HACK: Ignore 0x6b and 0x6f on cx88 boards.
* FusionHDTV5 RT Gold has an ir receiver at 0x6b
* and an RTC at 0x6f which can get corrupted if probed.

Convert this driver to v4l2_subdev. Note that currently the only card with
analog support in this driver is the HVR-1800. The analog tuner support in
this driver is limited to what is needed for this board. When analog support
is added for other cards, then the tuner load code will probably have to be
expanded to take care of those boards. For example, there is currently no
support for either radio tuners or tda9887 demods.
I'd like to thank Steven Toth for testing this on his HVR-1800.

Since i2c autoprobing will disappear bttv needs to be converted to use
v4l2_subdev instead.
Without autoprobing the autoload module option has become obsolete. A warning
is generated if it is set, but it is otherwise ignored.
Since the bttv card definitions are of questionable value a new option was
introduced to allow the user to control which audio module is selected:
msp3400, tda7432 or tvaudio (or none at all).
By default bttv will use the card definitions and fallback on tvaudio as the
last resort.
If no audio device was found a warning is printed.
The saa6588 RDS device is now also explicitly probed since it is no longer
possible to autoprobe it. A new saa6588 module option was added to override
the card definition since I suspect more cards have this device than one
would guess from the card definitions.
Note that the probe addresses of the i2c modules are hardcoded in this
driver. Once all v4l drivers are converted to v4l2_subdev this will be
cleaned up. Such data belongs in an i2c driver header.

This change allows bttv to use tvaudio for this device. Since this device
has the same i2c address as the tda9874 we need to support both in the same
tvaudio driver. This makes it possible for tvaudio to detect which chip is
used. Originally the tda9875 was only available in the dedicated tda9875
driver, but that makes life very hard for bttv since loading tvaudio might
misdetect a tda9875 as a tda9874.

Separate tuning table for DVB-C solves tuning problem at 388MHz
TechnoTrend C-1501 DVB-C card does not lock on 388MHz. I assume that
existing frequency table is valid for DVB-T.
This is suggested by the name of the table: tda827xa_dvbt.

Added runtime selection of the DVB-C table when the tuner is type
FE_QAM.
This should leave the behaviour of this driver with with DVB_T tuners
unchanged. This modification is in file tda827x.c

note also that with this change, the driver will no longer be usable
in kernels older that 2.6.22.

The v4l2-subdev infrastructure requires that an initialization call
must be issued to all attached sub-devices before normal operation can
start. This change satisfies that requirement.

When a pvrusb2 driver instance first initializes, we need to be sure
to send out a complete state update for everything to all attached
modules. The old i2c layer did this by keeping a separate mask of
"stale" bits for each attached module - and setting that mask to all
stale when that module attaches. But the new sub-device adaptation
I've implemented here no longer has per-module stale bits. So instead
there's now a global "force dirty" bit that is set upon instance
initialization, before the sub-devices are attached. After the first
update, this bit is cleared, allowing for normal update-on-dirty
behavior. In this manner, we ensure that all sub-devices have been
properly synchronized at initialization.

The tuner sub-device isn't going to work very well unless we tell it
the correct tuner type to use...

The sub-device update mechanism relies on various "dirty" bits in the
driver in order to know what pieces of state need to be propagated out
to the various sub-devices. But that won't work if the dirty bits are
cleared before the update gets a chance to run. This change ensures
that the update takes place before the dirty bits are cleared.
