In practice, the tuner occasionally fails to respond correctly after a
firmware load. Retry the firmware load if the firmware/hardware version
we read back from the tuner after programming does not match what we
expect.

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.

Hold the private lock over set_config and set priv->firm_size to 0 after a

Clean up the firmware load/error messages somewhat and rename priv->version

means that other I2C activity could occur in between and state could get out

to get any sound. The below patch selects this firmware variant on

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).

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.
