DVB-T did not work at all - only 6 MHz was working but it is not
commonly used.
Fix it.

This patch replaces the previous one proposed in the thread "xc3028:
force reload of DTV7 firmware in VHF band with Zarlink demodulator",
at the linux-media@vger.kernel.org ML.
The problem is that the firmware DTV78 works fine in UHF band (8 MHz
bandwidth) but is not working at all in VHF band (7 MHz bandwidth).
Reading the comments inside the code, I figured out that the real
problem could be connected to the formula used to calculate the center
frequency offset in VHF band.
In fact, removing this adjustment fixes the problem:
if ((priv->cur_fw.type & DTV78) && freq < 470000000)
offset -= 500000;
This is coherent to what was implemented for the DTV7 firmware by an
Australian user:
if (priv->cur_fw.type & DTV7)
offset += 500000;
In the end, now the center frequency is the same for all firmwares
(DTV7, DTV8, DTV78) and doesn't depend on channel bandwidth.
The final code looks clean and simple, and there is no need for any
"magic" adjustment:
if (priv->cur_fw.type & DTV6)
offset = 1750000;
else /* DTV7 or DTV8 or DTV78 */
offset = 2750000;

Now, ops->info.type is handled inside the dvb_frontend
core, only for DVBv3 calls, and according with the
delivery system. So, drivers should not care or use it,
otherwise, it may have issues with DVBv5 calls.
The drivers that were still using it were detected via
this small temporary hack:

The per-delivery system tables are confusing.
Add an extra table that explains them, and some
dprintk calls, that allows to check if mt2063 driver
is working as expected.

Instead of printing it just for debug purposes, outputs the detected
version at the logs. This may be useful if someone wants to report
a problem.

While here, improve a few debug messages that helped to track the
issue and may be useful in the future.

This also helps to identify when a device is not initialized,
if the bridge doesn't return an error for a I2C failed transfer.

Instead of crash, return -ENODEV, if the device is not poperly
initialized.
Also, give a second chance for it to initialize, at set_params
calls.

Several vars at set_parms functions were set, but unused.
Remove them and change the logic to return -EINVAL if the
analog set_param is used for digital mode.
At the analog side, cleans the logic that sets the several
analog standards.

No functional changes on this patch. Better organize the delivery

The driver were using a hacky way of setting analog and digital
frequencies. Remove the hack and properly add the tuner logic for
each supported type of standard.
I was tempted to add more standards there, like SECAM and to fix
radio (as stepping seems broken), but I opted to keep it as-is,
as tests would be needed to add additional standards.

Such code is disabled via ifdef's. Also, they're ugly and rely
on some static structures. Just remove. If ever needed, the git
log can be used to recover it.
