Fix all other remaining checkpatch.pl compliants on the Siano driver,
except for the 80-cols (soft) limit. Those are harder to fix, and
probably not worth to do right now.

Remove the remaining CamelCase checkpatch.pl compliants.
There are still a few left, but those are due to USB and
DVB APIs.

There are several structures defined in uppercase. Convert them
to lowercase, and simplify their names, when possible.

It is almost impossible to see a compliant with checkpatch.pl
on those Siano drivers, as there are simply too much violations
on it. So, now that a big change was done, the better is to
cleanup the checkpatch compliants.

Let's first replace all CammelCase symbols found at smscoreapi.h
using camel_case namespace. That removed 144 checkpatch.pl
compliants on this file. Of course, the other files need to be
fixed accordingly.

Implement poll() method for debugfs and be sure that the
debug_data won't be freed on ir or on read().
With this change, poll() will return POLLIN if either data was
filled or if data was read. That allows read() to return 0
to indicate EOF in the latter case.
As poll() is now provided, fix support for non-block mode.

Those fields help to identify the version of the ISDB stats.
Useful while debuging the driver.

To avoid mixing two different things at the same place, move the
debugfs code into a separate file.
