DVB-S is not supported. Also, there are some QAM6 firmwares for xc3028, but it
is reported that this doesn't work fine.
Thanks to Manu Abraham, Michael Krufky and Patrick Boettcher for their
insights.

A previous patch implemented support for non-OFDM digital TV. However, the
previous bandwidth ofdm parameter were left at the code by mistake.
Thanks to Michael Krufky and Patrick Boettcher for noticing this mistake.

s-code tables are related to IF frequency used for video demodulation.
The s-codes for analog are automatically loaded, according with video standard.
However, for digital, they will depend on the IF of the demoduler chip. IF of
the demoduler.
Before this patch, only a few IF's where possible to use. This patch allows
selecting any IF defined at firmware file.

Since check_firmware is called via analog or digital set freq routines, move
type selection to those routines. This avoids having several if's at the code,
and simplifies the source code.
A sideback effect is that implementing radio and other dvb types will become
simpler.

On some cases, xc2028/xc3028 wents into "turn off" mode. It seems that this
happens when very weak signals are tuned. To solve this, specific standard
reaload were done previously. Christopher patches changed this behavior to a
complete firmware reload.
This patch removes the hack. A much cleaner solution for this trouble is just
to sent a xc2028/3028 software reset.

xc3028 can be used on some DTV only designs (for example, DVB-S boards). Before
this patch, a DTV only board would need to call set_tuner_config callback.
This patch allows to optionally pass a xc3028_ctrl parameter, via xc3028_config
struct, fully initializing the driver for DTV.

Xc2028.3028 has two type of firmwares: audio-standard specific ones and
baseband MTS firmwares. MTS firmwares provide stereo decoding for 6 MHz
BTSC/EIAJ and for monoaural audio decoding on 8 MHz firmwares.
It seems that the option to use MTS or a standard-specific audio decoding
depends on the way xc2028/3028 is connected.
Instead of wasting 32 (or 64 bits) to signalize if the driver needs to use MTS
firmware, this patch converts it to a bitfield that can be shared with other
proprieties of xc2028/3028.

Define a list of valid "firmware types" for each combination of BASE,
DTV and SCODEs. By masking the appropriate firmware bits off we can
just use one "type" for the firmware searching and also flag when we
are looking for a BASE, DTV or SCODE type firmware. This makes it
much easier to track if we need to change device modes or flash an
individual firmware part.
Add a structure to remember what firmware properties we have. This
contains the currently loaded/wanted base firmware (type), video std
(id), video std requested (std_req), scode file and number in use.
Incorporate said structure into the tuner private data.
When checking whether the current firmware needs to be reloaded, first
figure out exactly what "type" of firmware we want (base, std and
scode), and then proceed to load the appropriate matching base,
std-specific and scode records iff there are any changes required.
This removes guesswork from the process because we no longer need to
individually code a check for every tuning parameter's interactions.

Rather than picking the first video standard firmware that supports any of
the standards that the user has requested, try to select one that supports
as many of them as possible. This improves the likelihood that the firmware
we select will support the user's desired TV standard.

There is no need to duplicate the max_len field from the ctrl structure
in the private data. If we use it directly from priv->ctrl, we can memcpy
the structure (apart from strings) to reduce maintenance as it grows.
Enforce a minimum max_len length of 8 data bytes (+ 1 address byte) as seems
to be required by the tuner.
Also, use kstrdup instead of open coding the string duplication.

Xceive 2028/3028 has a concept of scode/dcode.
Scode is a table of 16 values (each with 12 bytes i2c sequence).
Dcode is the entry of Scode table that should be used, given a certain
frequency.
The idea is that, depending on what frequency is selected, and according with a
country-based (or standard-based?) table, the Xceive should be "hacked" to
fine-tune that specific frequency.
By default, Scode=0 is used, for undefined frequencies. Also, Scode=0 seems to
be the most used value.
This patch adds the capability of selecting a scode. However, extra work will
be needed to allow auto-selecting the proper scode, for a given set of
frequencies.
I'm not sure what would be the proper way for implementing the dcode selection.
