b52e7c7687 [media] mt2063: add some useful info for the dvb callback calls 
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.

d1244f77d9 [media] mt2063: print the detected version 
Instead of printing it just for debug purposes, outputs the detected
version at the logs. This may be useful if someone wants to report

19ad6a01bb [media] mt2063: Print a message about the detected mt2063 type 
This also helps to identify when a device is not initialized,
if the bridge doesn't return an error for a I2C failed transfer.

1b0bfee39d [media] mt2063: don't crash if device is not initialized 
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.

2e1d5885f4 [media] mt2063: Rewrite tuning logic 
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.

99ac541254 [media] mt2063: Fix analog/digital set params logic 
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.
